Out of memory errors detected on your server

Featured Replies

orion-diagnostics-20260331-1648.zip

I'm noticed a "Out of memory errors detected on your server" error in "Fix Common Problems". I've created a diagnostic file and posted it here. I used to have 128GB but 2 DIMMs went bad and I'm down to 64GB.

After looking at the logs I found this:

I've since removed the Deprecated plugin ca.cleanup.appdata.plg.

I don't remember installing a RAM-Disk plugin so I'm not sure why Unraid keeps making a RAM-Disk. Is this new with the current version?

Ah wait I am apparently using "[Plugin] RAM-Disk for Docker logs"(https://forums.unraid.net/topic/185193-plugin-ram-disk-for-docker-logs/). Should I remove this?

Maybe, but it was tdarr that hit its limit and ran OOM and was killed. Change the config so it's work area is on a disk.

Reboot to clear the log so FCP stops warning you

Hmmmm.... but I constrained Tdarr's RAM usage to 16GB.

Extra Parameters = --runtime=nvidia --memory=16g



When you say "work area" do you mean this?

Yep, and that's why it was killed, it blew past the limit

You need to map /temp to a disk share in the tdarr_node container, or preferably an old SSD you don't mind abusing.

Sorry, Is this not that? Not being combative in tone. Really want to learn and fix this.

Yes, both the server and node containers should look something like this

Hmmm.... I believe I already have it set up that way. I have the transcode cache on an NVMe. maybe it's freaking out because it's not on the same share as the actual media files?

RAM-mapped paths don't count towards container RAM usage, so if the container got killed because it used more than 16G then it means it needs more than that for what you're doing

That looks right for the server, just make sure /temp is set up the same way for the tdarr_node container
