As mentioned this happens with kubo 0.17. I am facing the same issue. This is not an issue with snap or not but with the new libp2p code i guess which was turned on in 0.17. I have gone back to 0.16 for the moment.
I have tried to increase the inbound connection limits to no avail

2 years ago I accidentally changed the resource in the wrong server, so changing the inbound connection value does work.
So changing the inbound connections to 1024 cured this for me. So add to your .ipfs/config in the "Swarm" block the following then you can tweak as you need.
"ResourceMgr": {
"Limits": {
"System": {
"Memory": 1073741824,
"FD": 512,
"Conns": 1024,
"ConnsInbound": 1024,
"ConnsOutbound": 1024,
"Streams": 16384,

}

2 years ago Also ran into this problem. My error message is:
Application error 0x0: conn-12133298: system: cannot reserve inbound connection: resource limit exceededWe are running a customized 0.17.0 build.
We are running an experiment to measure the lookup latencies in the IPFS DHT network. For that we have deployed several, customized kubo nodes. The customization consist of just additional log messages. One of these log messages is right after the GetProviders RPC here:
It logs the return values. I noticed that I receive a lot of the following errors:
Application error 0x0: conn-12133298: system: cannot reserve inbound connection: resource limit exceededTherefore I went ahead and disabled the resource manager (see config above). The error messages still stick around. Then we just deployed more beefy machines and the errors seem to be less but they still happen frequently.
It's also weird that the error message talks about an inbound connection although I'm calling out to the remote peer 🤔 .

2 years ago This error is expected when you have too many inbound connections at the System level to avoid DoS attacks. If your hardware or use case needs to support more inbound connections than the default, you can change that by doing:
# Remove custom params
ipfs config --json Swarm.ResourceMgr '{}'
# Set inbound connection limits to a custom value
ipfs config --json Swarm.ResourceMgr.Limits.System.ConnsInbound 1000
# You might want to change also the number of inbound streams
ipfs config --json Swarm.ResourceMgr.Limits.System.StreamsInbound 1000
# If your hardware configuration is able to handle more connections
# and you are hitting Transient limits, you can also change them:
ipfs config --json Swarm.ResourceMgr.Limits.Transient.ConnsInbound 1000
ipfs config --json Swarm.ResourceMgr.Limits.Transient.StreamsInbound 1000
# Remember to restart the node to apply the changes
# You can see the applied changes executing:
$ ipfs swarm limit system
$ ipfs swarm limit transient
# You can check actual resources in use:
$ ipfs swarm stats system
$ ipfs swarm stats transientThe error is followed by a link: Consider inspecting logs and raising the resource manager limits. Documentation: https://github.com/ipfs/kubo/blob/master/docs/config.md#swarmresourcemgr
There you can learn about all the different knobs to tune ResourceManager, but the more important ones are ConnsInbound and StreamsInbound.

1 year ago Potentially a controversial take, but this feels like UX problem, and not a problem with default limits.
Printing error every 10 seconds when any limit is hit is bit hardcore. We have limits for a reason. They are feature. This constant ERROR messaging makes them feel like "error that needs to be solved by raising/removing limits", which is imo UX antipattern.
:point_right: ResourceMgr protecting user and working as expected should not look like ERROR.
Quick ideas that would remove the need for relaxing default limits:
Resource limits were exceeded with ResourceMgr protected node from exceeding resource limits Swarm.ResourceMgr.VerboseEnforcement Flag set to true by default, when set to false removes ERRORs or moves these messages to WARN or DEBUG level.
To remove this message set Swarm.ResourceMgr.VerboseEnforcement to false (most users won't be able to reason what limits should be changed, and would like the message to go away – we would want to suppress log spam it in GUI apps like ipfs-desktop and Brave too).Potentially a controversial take: maybe there is an UX solution to this?

1 year ago @lidel if we bump errors to be printed every hour, you won't notice when you really are hitting limits. Let's say that you hit limits at 1:01 PM then until 2:00 PM you won't have any kind of information, and the limits at that time are just fine, but you are having a warning or an error because you hit limits one hour away.
We can make it possible to silence the error output, but the problem won't disappear. Nodes with better hardware will struggle to handle incoming connections even if they have enough real resources, and small nodes will be like they don't have any resource manager active because default limits will be too high.
My proposal is to set default resource manager limits per peer only by default. It is the only limit that we can set by default knowing that will be right for any user and any hardware: https://github.com/ipfs/kubo/pull/9443 The ideal solution will be to limit to only one connection per IP but it is something that is not straightforward.
lidel
commented
1 year ago Ack on reporting this early – fair enough. For now, proposed cosmetic message adjustment in https://github.com/ipfs/kubo/pull/9444 but we still suggest user should raise limit – and it is the only way for log spam to go away.
I am not sold on per IP/peerid limits being enough. Adversary could:
Having a default global limit for incoming connections is really useful.
Unsure if there is a silver bullet, but UX solution feels way less risky
I would add Swarm.ResourceMgr.VerboseEnforcement flag as a way to move messages out of ERROR log level, and keep global limit, just to be safe, but maybe there is a better way?
kallisti5
commented
1 year ago @lidel any idea though on why i'm seeing "random" limits when ResourceMgr is {} on upgrades?
That feels like a bug. When ResourceMgr is {}, the values seemingly are set randomly. Thinking it's an upgrade issue.
This bug can be reproduced by:
ipfs config --json Swarm.ResourceMgr '{}'ipfs swarm limit system
BigLep
commented
1 year ago Ok, there's lots to unpack here...
Below are the problems I'm seeing...
https://github.com/ipfs/kubo/issues/9432#issuecomment-1327647257 and other comments said they disabled the resource manager but are still seeing messages in the logs. In that commend, we can see it's disabled in config:
"Swarm": {
"ResourceMgr": {
"Enabled": false
},4611686018427388000 is actually not a magic value. It is effectively "infinity" and is defined here: https://github.com/ipfs/kubo/blob/master/core/node/libp2p/rcmgr_defaults.go#L15
Swarm.ResourceMgr is set to {}I believe in this case we are setting default values as described in https://github.com/ipfs/kubo/blob/master/docs/config.md#swarmresourcemgr.
There is confusion about what messages like mean
"system: cannot reserve inbound connection: resource limit exceeded". For this example, it means Swarm.ResourceMgr.Limits.System.ConnsInbound is exceeded. It would be nice if the value from ipfs swarm limit system was included.
When a resource limit is hit, we point users to https://github.com/ipfs/kubo/blob/master/docs/config.md#swarmresourcemgr. It's clear from the feedback here that the docs there aren't actionable enough.
I don't think we should discuss this more or pursue it. As discussed in https://github.com/ipfs/kubo/issues/9432#issuecomment-1334482153, it is ineffective and impacts NATs (especially large organizations/enterprises which have all their traffic coming from behind a NAT).
There is good commentary on this in https://github.com/ipfs/kubo/issues/9432#issuecomment-1334160936.
I agree with this sentiment in general. go-libp2p bounding the resources it uses is generally a feature, and the presence of a message doesn't necessarily mean there's a bug.
That said, if by default our limits are crazy low, then I would call it a bug. For example, if Swarm.ResourceMgr.Limits.System.ConnsInbound was set to "1" by default, I would consider it a bug because this would mean we'd only allow 1 inbound connection.
Using https://github.com/ipfs/kubo/issues/9432#issuecomment-1331177613 as an example, Swarm.ResourceMgr.Limits.System.ConnsInbound is set to 123. This is derived from Swarm.ResourceMgr.MaxMemory. I assume @kallisti5 didn't set a MaxMemroy value and the default of TOTAL_SYSTEM_MEMORY]/8 was used per https://github.com/ipfs/kubo/blob/master/docs/config.md#swarmresourcemgrmaxmemory. (In this case TOTAL_SYSTEM_MEMORY looks to be around ~16GB as 1999292928*8/(1024*1024) = ~15,253)
ajnavarro
commented
1 year ago For all people who are having resource manager errors, could you try executing the following command? ipfs config Swarm.ResourceMgr.MaxMemory "HALF_TOTAL_MEMORY" where HALF_TOTAL_MEMORY is a string value like 16GB.
Complete command:
ipfs config Swarm.ResourceMgr.MaxMemory "16GB"
The default value right now is 1/8 of the total memory. Setting this value to 1/2 of the entire node memory will increase the number of inbound connections allowed and hopefully reduce resource manager log errors.
Note that after executing the command, you need to restart the node to take effect.

1 year ago @BigLep: Use case on this for consideration. I run multiple very large (some 2TB+) ipfs servers on VM's and sometimes change the memory allocated to them.
Fixing the memory to half of the current memory is something that I'm reluctant to do because I may have a server using 16GB, but due to host hardware constraints from time to time I may need to reduce it to 8GB, or expand it.
I would desire that service running on the system self adjust for this change and utilize the available memory
Setting the Connection Limits based on system memory is a great idea. However in my case, these are dedicated ipfs servers so the 1/8 of system memory default is too small. On the other hand 1/2 of system memory is too big for the ipfs server I'm running on my development workstation.
A literal macro type setting such as, HALF_TOTAL_MEMORY, EIGHTH_TOTAL_MEMORY seems like would be optimal for my use cases rather than fixing these limits in the config file.
init profiles for Server could apply HALF_TOTAL_MEMORY, and the default could remain at eighth.

This seems odd given ipfs config Swarm.ResourceMgr.MaxMemory "8GB". It looks like 16GB was actually being passed.
I still seeing resourcemanager errors.
It would be helpful to know the error message so can confirm, but it looks like it would be for System.ConnsInbound (which is a value scaled based on Swarm.ResourceMgr.MaxMemory.
I also got this message during startup, which I think is new
I personally don't know what this is, but it's likely separate and won't be triaged here.
We're tracking the various followups we're active on here: https://github.com/ipfs/kubo/issues/9442 . One thing we expect will help is to lower your ConnMgr limits below System.ConnsInbound. There is some discussion about this in https://github.com/ipfs/kubo/pull/9468 (search for "How does the resource manager (ResourceMgr) relate to the connection manager (ConnMgr)?")

}And to confirm, here's the excerpt from my config file under "Swarm":
"ResourceMgr": {
"MaxMemory": "8GB"
}The service was restarted after the config file change this morning, and the ConnsInbound limit did increase from a previously hardcoded 500, and even previously default level of < 200 after ResourceMgr was cleared and only MaxMemory was set.
And here are the console errors from journal:

Documentation: https://github.com/ipfs/kubo/blob/master/docs/config.md#swarmresourcemgrI'm not surprised to get more connections to this server than I can handle, there's a lot of good stuff here, I agree with previous sentiments that these errors are too much noise though, also since they are level of ERROR.

460@2color Yes. These errors are from other peers you are connected to. You should enable ResourceManager to avoid DoS attacks. Here are all the pending issues on RM:
This one is the specific one for your case:

1 year ago @Derrick-
I don't understand the Memory limit result, it does seem to claim 16GB.
Doh - that's a bug. It's being fixed here: https://github.com/ipfs/kubo/pull/9470
@rotarur
yeah this error is noisy and my system limits are never reached as well:
ACK on this "error" being noisy. This is being tracked in https://github.com/ipfs/kubo/issues/9442 and handled in https://github.com/ipfs/kubo/pull/9472
That said, in your output you only shared the "system" scope. There are other scopes that could be exceeded. Ideally you would be able to do to ipfs swarm stats --min-used-limit-perc=90 all to pinpoint this, but there is a bug (doh!): https://github.com/ipfs/kubo/issues/9473
In the interim, you can inspect the log message more to understand what scope and what limit within it is being breached. We have some docs drafted in https://github.com/ipfs/kubo/pull/9468 to help with this. Search for "What do these "Protected from exceeding resource limits" log messages mean?"
@2color Yeah, this is understandably confusing. To help alleviate until things are clarified on the go-libp2p side, we have docs in https://github.com/ipfs/kubo/pull/9468. Search for "What are the "Application error ... cannot reserve ..." messages?". Given the challenges we've been having with resource manager enablement in Kubo, we'd certainly welcome your feedback on that PR.

1 year ago Protected from exceeding resource limits" log messages mean?
thanks @BigLep ❤️ Your documentation helped me to understand where this error comes from in this line
This can be confusing, but these `Application error ... cannot reserve ...` messages can occur even if your local node has the resoure manager disabled.So my errors are from remote nodes and not mine. How this error can be addressed?

1 year ago I accidentally changed the resource in the wrong server, so changing the inbound connection value does work.
So changing the inbound connections to 1024 cured this for me. So add to your .ipfs/config in the "Swarm" block the following then you can tweak as you need.
"ResourceMgr": { "Limits": { "System": { "Memory": 1073741824, "FD": 512, "Conns": 1024, "ConnsInbound": 1024, "ConnsOutbound": 1024, "Streams": 16384, "StreamsInbound": 4096, "StreamsOutbound": 16384 } } },
add it without last comma as it will make errors with config file
"ResourceMgr": {
"Limits": {
"System": {
"Memory": 1073741824,
"FD": 512,
"Conns": 1024,
"ConnsInbound": 1024,
"ConnsOutbound": 1024,
"Streams": 16384,
"StreamsInbound": 4096,
"StreamsOutbound": 16384
}
}
}I'm going to resolve this since we aren't getting new reports here and we have the fixes mostly handled (and at least being tracked in https://github.com/ipfs/kubo/issues/9442 ). If after 0.18 we get new issues, we'll coalesce and create additional resulting issues.

1 year ago I'm still seeing this after updating to 0.18;
My setup is a publicly-routable node, with a system inboundconn limit of 5000, which this does not hit at all.
None of my limits are getting even close to being hit, and i'm also seeing the above immediately after the daemon has finished booting;

1 year ago I'm downgrading to 0.17 again, after https://github.com/ipfs-cluster/ipfs-cluster/issues/1835 makes it not possible to use it for me.

1 year ago I had the same problem and it was coming from that all the ports aren't well opened in ufw

1 year ago I'm running on Debian 10, @sven-hash could you elaborate on that? What do you mean "not properly opened", so you mean that only some ports were, or that some ports had some specific filtering?

The port 4001 in UDP wasn't open in the security group on VPS cloud provider side so it was not accessible and after sometime the cluster crashed. Since I open all the port correctly in UDP and TCP I never have a crash

1 year ago I just checked, it doesn't seem my VPS provider (hetzner) has any firewall rules or such in place

1 year ago I have since then changed the log level to error, and after 9 hours, i'm observing my pinning process going well, so for me the matter is relatively solved.

1 year ago FWIW yesterday i used to occasionally ipfs ping my own node, and observing the following;
jonathan@os-mule:~$ ipfs ping 12D3xxx
PING 12D3xxx.

Error: ping failedThis was while the system stats were way under limits, so I don't know why the other side would close this stream early. This also happened simultaneously with a staggered pinning process, so I don't know what happened there.
Pinging now seems to go alright. Inbound conns is about 800-1000, while it reached a high of 3000 yesterday.
I wonder if due to the contention of restarting IPFS a bunch of times, the linux network buffer is overloaded. I did not get any kernel messages or the likes, but for a while, reaching the node was very unreliable.

1 year ago After seeing this problem with 0.18-RC1, I upgraded to 0.18 today, and reproduced the same problem as reported by @ShadowJonathan and by me earlier on two different machines.
Machine 1 (running on fly.io): 2GB Ram, default 0.18 config

1 year ago @2color @ShadowJonathan Please have a look into Theme 3: improve RM errors coming from other peers section here: https://github.com/ipfs/kubo/issues/9442
TLDR: These errors are errors coming from remote peers that are hitting Resource Manager limits, not the local node. Note the (remote): flag on errors before the connection manager error.

1 year ago Ah, I had that suspicion, but I wasn't entirely sure if this was indeed the case. Thanks for pointing to the (remote) marker, that makes those log entries a lot more understandable, as it was US-daylight hours, with the nodes most likely more overloaded at that time 😅
Then that addresses all my concerns for me personally, except the stall on ping during those hours, that is still a mystery to me.
The log entries could be made more clear if (remote) is turned into (from remote), else it's easy to confuse this as being related to remote something, not that it is coming from the remote node. I'll echo this in the issue you linked as well.

Description
Trying to run IPFS on VPS.
Error Description: The node starts, show success swarm announcing addresses, the port 4001 is exposed externally ( I checked) and after a few seconds it closes and I got this error message:
ERROR resourcemanager libp2p/rcmgr_logging.go:53 Resource limits were exceeded 496 times with error "system: cannot reserve inbound connection: resource limit exceeded".Then the port cannot be reached anymore
Error occurend on both Docker (20.10.21) and installation from binaries
