Flint memory leak ？

alzhao · 2021-11-15T05:34:20.747Z

Did you use adguardhome? When this happen, can you ssh to the router and check using ps?

No AdGuard Home enabled, only NextDNS DoT configured and pure Wi-Fi serving and WireGuard server running.

The ps command listing output I can’t see any specified process take a lot of memory usage, most of them the maximum only take around 1.2% usage and the total amount of the processes take seems not match that much memory as shown in the App statistics.

Understood. Will investigate the same scenario.

I have the same problem, my network after i connect to ax1800 reboots frequently, after i check it before reboot the memory total used by the process is 98%, after reboot the memory going back to 88%.

Please fix this memory leak problem

after reboot, my Flint memory is around 73% then it will increase around 1% every day…

Willowen:

after reboot the memory going back to 88%.

My memory usage after reboot is 66%. What server did you turn on?

Willowen · 2021-11-16T09:06:44.223Z

I only use adguardhome, i don’t install any addon.

Hi cafebug:

Could you help me check some information?

Login via ssh ，then exec the following：
pid=$(pidof AdGuardHome);cat /proc/$pid/status

Then send me the screenshot.

Thanks!

cafebug · 2021-11-17T10:27:06.295Z

actually, I never have AdGuardHome turned on, so your command doesn’t work.

Ubermensch · 2021-11-18T11:41:31.949Z

Same problem for me. Memory at 96% but with adguard on

cafebug · 2021-11-18T11:44:21.327Z

Yes, the memory leaking problem is pita.

alzhao · 2021-11-18T11:46:45.162Z

Can you ssh to the router and use the following command to see if the RAM will drop?

echo '3' > /proc/sys/vm/drop_caches

Pls let me know the result.

cafebug · 2021-11-18T11:47:43.260Z

Let me try it and report back …

cafebug · 2021-11-18T11:51:40.763Z

Before & After Command: (It works ) (78% —> 62% )

alzhao · 2021-11-18T11:52:32.730Z

OK. Thanks very much.

Seems we identified the problem. Pls wait for the new firmware. Compiling asap.

alzhao · 2021-11-25T03:45:49.298Z

Hi morcheba:

Memory is increased as the system runs. But will be freed when the system needs to use memory.
