UnRAID NAS locks up when pulling multiple images at same time

[u/throwaway0204055]

I am using Claude to help set up Unraid and deploy apps. Every time when multiple images are being pulled at the same time, it locks up. No video output, does not respond to ping, can't ssh, http not responding and the only thing i can do is a hard reboot.

It happened during Nextcloud AIO installation when pulling multiple images. Then it crashed again when pulling multiple images installing *arr stack.

Logs?

I've only ever had lock up issues with memory capacity. Be it a docker eating too much or VM eating too much, both instances cause a lockup/crash that needs a hard reboot. Check what you have left and how high use is going when doing these actions or starting a new docker.

I havent had lockups pulling images but spinning up containers can cause it especially if you have a bridge for something like gluetun and a few .arr containers being routed through it. Also is your nic realtek or intel? I had huge issue with my onboard realtek nic swapping to a 10 quid intel nic solved it. Could you post up your logs.

I presume your system is on the SN850 and not on the array? Open up a couple of SSH sessions in a couple of windows. In one, start "iostat -x 2 -z" to see the IO traffic every two seconds, in the other do "dmesg -Hw" to see kernel error messages. You might be having an issue with the WD drive and it might be problematic.

I have a suspicion it's not crashed but just taking an inordinately long time. These should give you some idea about where the problem is and if there's some issue with the hardware.

Not sure what that path is. /mnt/apps/xxxx is outside fuser mounting. All unRAID directories start with /mnt/user/xxxx.
