Increased memory usage on WRT3200ACM #152

Closed admiral0 closed 7 years ago

admiral0 commented 7 years ago

Hello,

I noticed that the 3200 has a "resting" memory usage of 190Mb RAM. When I start transfering data heavily (300 MBits/s) it starts to use more memory until the system reboots.

  1. Any tips on how to debug this without a serial console on lede?
  2. This doesn't look like a memory leak, because it goes back to "resting" values if I stop transfering.

More info. I am running lede trunk, and latest master from this repo.

Fr3DBr commented 7 years ago

@Chadster766 do you know when Linksys will push a firmware with this update ? It is very important for WRT3200 customers.

Chadster766 commented 7 years ago

Linksys engineering doesn't provide me with firmware release ETAs.

AFAIK the Linksys firmware wireless driver isn't the same as this one.

Fr3DBr commented 7 years ago

@Chadster766 I know, but the stock linksys firmware, also have multiple issues even with latest firmware. So just guessing if they would update it soon. (My friend has a WRT 3200 that requires to be rebooted every 24 hours due to a freezing issue, maybe related with this memory usage issue...).

kb3tbx commented 7 years ago

Getting back to the Open-Source driver, mwlwifi AFAIK (which is little) this is OK lede capture

used my easy tests, as before, using both radios - nothing funky w/ memory use

Thank you for tracking it down.

yuhhaurlin commented 7 years ago

If there is no negative test result until next week, I will close this issue. Thanks.

Running my WRT3200ACM for nearly 2 days without issues using Firmware: DD-WRT v3.0-r32014 std (05/12/17)

I've got alot of this messages in Syslog, I have my 5Ghz in channel 52 which is a DFS channel, this is just an information of changing the frequency?

I cannot confirm of issues during this time because I was slepping...

Sorry for not talking about the subject.

Almost 24 hours up here and everything's good, love this driver! :)

yuhhaurlin commented 7 years ago

@s-pimenta The message is not from mwlwifi. BTW, I think mwlwifi is running for phy0 and phy1.

yuhhaurlin commented 7 years ago

@adi-brasov What do you mean closing?

yuhhaurlin commented 7 years ago

It is possible that client does not seed out deauthentication or disassociation . I will check inactivity checking If the device still exist after 300 seconds?

yuhhaurlin commented 7 years ago

O.K. I will check inactivity checking. Thanks.

kb3tbx commented 7 years ago

using it on 5ghz -> conn stays on. the led activity on 5ghz is on after more 300 sec , in fact it never turn off until I turn off wifi on router.

@adi-brosov: which 5ghz radio do you speak of? My Radio0 works. I switch a 5gig client to 2.4 (Radio1) and one LED goes out right away. I do not use Radio2! If I unplug a USB dongle from a laptop running at 5Ghz, the LED on WRT3200ACM goes out in under a minute.

Though, this should be made a new thread.

aaron1959 commented 7 years ago

"It is possible that client does not seed out de-authentication or disassociation"

aaron1959 commented 7 years ago

So are you absolutely sure the 'client' itself is acting the same on both bands? ie. deauth or dis? Basically the same question again waiting for your answer.

ValCher1961 commented 7 years ago

Somehow this does not apply to memory

aaron1959 commented 7 years ago

Yep yuhhaurlin started answering him but you are correct I don't think it belongs here. sorry for responding myself.

yuhhaurlin commented 7 years ago

The problem is easy to check, I will check it later. It is better to create another issue to track it.

yuhhaurlin commented 7 years ago

Since there is no negative test result about this issue. I close it now. About inactivity checking, I will check it later.

kb3tbx commented 7 years ago

I concur!

better than 6 days uptime here

uptime capture

yuhhaurlin commented 7 years ago

Yes. This fix is also applies to proprietary driver and the same problem is also gone. The driver is pretty stable now. Thanks all your help.

alexsmartens commented 5 years ago

Hi all, I’m also seeing ~180 Mb ram usage after a clean install of both OpenWrt and DD-Wrt into my new wrt3200. I’m a newbie in these systems, but this doesn’t seem right. Can someone give a recommendation of how to fix this?

eduperez commented 5 years ago

A high memory usage is not necessarily an issue, there are circumstances where it could be normal or even desirable: https://jameshfisher.com/2017/11/29/unix-free-used/

On the other hand, as other users around here have not had this kind of issue, even if this is an issue, it's unlikely to be caused by these drivers.

TL;DR: We need more details!

inteliboy commented 5 years ago

If you unload or completely remove the mwlwifi driver you will see that the RAM usage drops to about what you would expect. On my case around 30MB.

eduperez commented 5 years ago

Could you compare the output of lsmod and ps before and after removing the drivers, please? This will give us a better idea of where is that memory going.

@inteliboy is right. I can confirm I see the same behavior. I run OpenWrt 18.06.4, r7808-ef686b7292 and removing kmod-mwlwifi drops down the ram usage from 180-170 MB to 30-20 MB.

Check out my lsmod and ps logs below

Everything seems identical, except the obvious "mwlwifi" module (but it does not seem to be occupying so much memory) and the memory usage. Looks like the module is allocating the memory. Perhaps the contents of "/proc/meminfo" will give us more info.

@eduperez, what do you think? Can I help with something else?

alexsmartens commented 5 years ago

@yuhhaurlin, @kaloz, @BrainSlayer any thoughts?

c--- commented 2 years ago

I'm seeing some similar to this on the latest builds 22.03 from git but the RAM usage doesn't seem to grow unbounded. Two nearly identical routers but they use slightly different WiFi firmware versions, WRT1900ACS and WRT3200ACM.

The 1900 uses a normal amount of RAM but the 3200 is ridiculous. Removing the mwlwifi driver module releases a ton of RAM.

Such as the life of proprietary firmware, eh? :(

inteliboy commented 2 years ago

This driver is unfortunately dead and it is what it is.

I personally sold my WRT3200ACM and bought Netgear R7800.

Best regards

@eduperez, what do you think? Can I help with something else?

Development has been dead for years now, there is no hope of any improvement.
