Unraid memory problem: "Memory cgroup out of memory: Killed process 4157 (nginx)"

Featured Replies

Hello,

I keep getting errors that my memory is full on my server and eventually it kills nginx to remedy the issue. I have not noticed any major performance issues. I'm unsure how to start troubleshooting this and my case seems different than every other forum post I have read so far. 

 

Any pointers are appreciated. Thanks.

If it keeps happening try limiting more the RAM for VMs and/or docker containers, the problem is usually not just about not enough RAM but more about fragmented RAM, alternatively a small swap file on disk might help, you can use the swapfile plugin:

I have one VM running w/ 2gb on RAM assigned and at any point plex and deluge are using 2-3gb ram each, max. Every other application is using almost no ram and I have 4x 16GB sticks in the system right now. Could it really be fragmented ? Should I just get a few more sticks of ram?

 

I don't think swapfile is an option for me as I have use a BTRFS cache pool in RAID 1.

Could be, something is causing the OOM errors.
