[MrVb0]

Hello I use XRAYR and V2BOARD But the connection is disconnected every few seconds, and when I saw the log, I noticed this error :

Please help me to solve the problem

[Septrum101]

Cannot recall, could you provide the condition and config.yml?

[MrVb0]

In config.yml everything is normal I have this problem on almost every 10 servers I have, along with many disconnections It disconnects every few minutes and connects after a few seconds It is a boring situation Could this problem be related to v2board?

[pocketW]

Are you using the global device limit with redis right now?

[MrVb0]

Hello, yes, I have created a separate server for Redis and connected all servers to one Redis server

[MrVb0]

This setting information is related to global device limit I have connected all xrayr servers and all nodes of each server to a separate redis server.

[pocketW]

Similar issues #111 #131 have been reported. We thought this issue has been fixed after the refactoring of the global device limit. Since you are using the latest version (v0.8.8), we might need to further investigate this problem. Thanks for your reporting again.

[MrVb0]

Thank you for your reply. So I will wait for the new update. Thank you for making and updating this great script

[mokhtarabadi]

I have the same problem, but GlobalDeviceLimitConfig is disabled. I used PMPanel, ProxyProtocol, Nginx stream, and Trojan I edited pmpanel.go to add support for ws and h2

[mokhtarabadi]

@pocketW if you need tell me I will share my server details so you can check it, I have about 500 active users and now they have bad experience with panel, I think this is emergency bug

Hi, sorry for the inconvenience. Please kindly provide the configuration file and log if possible. Besides, could you also try to use the old version to see if the problem still exists? You can install the old version by using XrayR install v0.x.x.

I think it could happen in this case, due to some reason the UDP conn has closed, But the dispatcher still xfer the traffic to the UDP conn.

I first used the master branch, and I encounter the bug (also enabling/disabling global device limit not affected)

the problem does not appear in version v0.8.3

I think this is xtls bug

[mokhtarabadi]

@pocketW @thank243, the bug appears in version 0.8.3, but is very lower than in the latest version, for example, a crash occurs every 1 minute in the latest version but in 0.8.3 it occurs every 40-60 minutes

Ever since I set the global device limit to "false" and set the device limit to "0" and completely removed the speed limit in v2board (set it to 0), I feel that the disconnection and problems have decreased a lot. I felt that maybe telling you this will help you solve it. Thanks

[pocketW]

Thanks for your guys reporting the details. Just to check. Are you all using the Trojan? Does this bug also happen to other protocols like Shadowsocks and VMESS? I found all the logs saying this bug happened when using the Trojan.

[MrVb0]

I have both trojan and vmess on all my servers and I don't know which one is the problem . Thanks

[mokhtarabadi]

@pocketW I used only the Trojan protocol, and I don't know about vmess or others, Thank you too

[MrVb0]

In the past few days, I did different tests to find the main fault. First of all, I set the "global device limit" to "false" and set the "device limit" to "0" and completely removed the "speed limit" (set it to 0) After this, as far as I checked, this error was no longer observed and disconnection and disconnection became much less. So the problem is one of these things!

So I tested one by one:

In the first step, I set "Device limit" to "2", (while "Global device limit" was still "false") No error was observed at this stage.

In the second step, I set "Speed limit" to "100", No error was observed at this stage either.

In the next step, I set "Global device limit" to "true" again! And after a few seconds and a few "warnings" about device limitations, this error appeared again!!

According to my research, I am sure that "Global Device Limit" directly or indirectly causes this error. But I really need this feature and I am asking you to "please" solve this problem, thank you very much.

[mokhtarabadi]

I understand increasing device limit locally means in xrayr config will fix problem for a long time, until one user reaches the limitation, even when global device limit is enabled

Clone xray-core repository, apply the @pocketW PR, in XrayR add a link to your xray-core instead original version, and then build XrayR or send me a PM in telegram I'll send my built

One thing I just noticed: In addition to v2board, I also used sspanel One of my Xrayr servers is connected to sspanel. As you know, the global device limit feature is also available in sspanel When I updated the xrayr server that was connected to sspanel to version 0.8.8, I immediately encountered the same error!!! (invalid memory address or nil pointer dereference) And when I downgraded to the previous version (0.8.6) the problem was solved!

The PR has not been merged into the Xray-core. We will update the fix once it has been merged. The current commit does not fix this issue. Besides, you can also fork my PR in Xray-core and replace the dependencies with it to test.
