Out of memory errors detected on your server - Diagnostic Attached

[JeanLuc]

Hello unRaid community! I received an `Out of memory errors detected on your server` warning from Fix Common Problems. At the time this occurred, only a single Hass.io VM and my standard docker containers were running. This is the second time I received this warning, which I followed advice and rebooted and have not received this issue for the last couple weeks.

 

After downloading the diagnostic files, I found these three lines that appear to correlate with the memory issue. The top one seems to be the actual issue (others notification), but I don't see any unique ID that associates the issue with the VM/issue.

Any suggestions?

If it's a one time thing you can ignore, 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:

Thank you Jorge! I’m always cautious, wanting to learn and didn’t want to sweep this under. I’ll be paying better attention to my allocations. I’m only running 32G and quite a few services and was most likely pushing the limits. Thanks again.

I want to mark this as solved. I have not experienced this issue since posting.
