Hello,

looking for some support to see why my system keeps crashing each night and I need to use my kvm to manually reset the server most mornings since being above 7.2

I changed to an industrial SD card in a sandisk mobilemate reader, in a new usb port and that seemed to fix the issue for a month+ but then I tired to go to 7.2.3 from 7.2.2, and it started up again this week. So I rolled back to 7.2.2 but its still crashing. I tired to use ai to go through my syslogs and diagnostic files, but I think I need some help here.

Recent attempts at fixes... (the swapping USB drive/port seemed to solve it until the 7.2.3 update/downgrade

• New SD card in new usb port on mobo

• looking for high resource services and limiting RAM usage where I could see potential issues

• uninstalled unused plugins

• ran MEMTEST for 24hr (Passed)

THANK YOU IN ADVANCE!

Enable the syslog server and post that after the next crash.

Ope, sorry thought that was included with the Diagnostics if i had it enabled already.

Here it is from back when I first had to "fix" it with the new flash drive around thanksgiving.

Most recent crash was early in the morning on the 26th and 27th I believe

syslog-192.168.200.9.log

On the 26th there's an OOM event, and also this:

Dec 26 09:33:59 NASRUN php-fpm[15123]: [WARNING] [pool www] child 87621 exited on signal 9 (SIGKILL) after 897.728771 seconds from start

In my experience, these errors can be the result of the server being close to exhausting the memory, GUI can become extremely slow, like 1 minute to open the dashboard, try limiting the memory for VMs/docker services, or adding a little more RAM.

It could also be one or more containers hogging the CPU, try pinning only some cores to them, and leave cores 0/1 available for Unraid.

Also, recommend trying a couple of other things, go to Settings - Global share settings and set the Number of fuse File Descriptors to the max, and enable this

Thanks! I'll try all that and hopefully I can get back to 90+ days of uptime 🤞

Unfortunately after all those another crash at some point in the middle of the night.

I tried to find apps that were transcoding or caching to ram such as unmanic and changed it to my nvme drive. As well as limiting CPU usage on some containers and made sure I pinned everything even the non intensive apps.

Here's the most up-to-date syslog

syslog-192.168.200.9.log

There was an OOM event yesterday; a shell script running inside a Docker container was using around 23GB of RAM by itself.

task_memcg=/docker/2f561f642fdff61546b4370ae12d03fb84e4740f1b006a361f76ea6525a27e8d

The container ID is 2f561f642fdf

See if you can find it and either limit its RAM usage or temporarily disable it.

Woah! That would explain things! I think I did add that app about 2 months ago.

It was Autoheal, which I had running but not fully configured.

Think I'll bail in that and try our Healarr or something to keep my cloudflare tunnels up since they sometimes go dead on me.

Thank you! Hopefully that will do it!
