Out of memory errors


Recommended Posts

Posted (edited)

Hi all.

 

After a few days I am getting the Out of memory error in the syslog and the docker service to stop (all apps down)

 

I post here the logs before rebooting if someone can help me. Thank you.

 

I currently have 32GB RAM in the server with only 1 VM with 2GB of RAM assigned. The rest Docker containers.

 

kernel: Out of memory: Killed process 12305 (dockerd)

Yes, or 4G.

I don't really know any I installed. Do you mean like installing proxies? Sorry about the question.

They should be related to one of the containers you are running, try just limiting the RAM for Jellyfin for now, also, I think you should also check that you are not transcodig to RAM.

Docker daemon itself got killed because it was using a lot of RAM, still seeing a lot of docker-proxy processes, but don't know which container is creating them, you will need to try and find out which container is causing the issue, unless someone else has a better idea, you can try running half of them, if the issue remains try the other half, then keep drilling down.

OK, sorry but where do you see the proxies? in what log? Thank you, will try the half-half method.

Look in the syslog-previous, when there's an OOM event, it list all the running processes, and there are tens ( or hundreds) of these:

This is not normal.
