November 12, 20232 yr Hi everyone, since a few month my Unraid server starts showing the error: "Out Of Memory errors detected on your server" out of nowhere every month or so. Reboot fixes it but seems not to be a fix. I'm not sure where to look in the diagnostics files. Could you please support me in finding the problem? Thanks in advance! Newest Diagnostics are attached homeserver-diagnostics-20231112-1601.zip
November 13, 20232 yr Community Expert 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: https://forums.unraid.net/topic/109342-plugin-swapfile-for-691/
November 13, 20232 yr Author Not enough RAM is definitely not the issue here. I have 64GB installed and the server does not use more than about 25% on average at the moment. But I honestly never thought of fragmentation. Ok, I will start with limiting RAM for docker containers. Some already are limited, the latest ones I installed are not. Since the issue happens only once a month or so, my next update after trying your suggestions might be not in the near future
December 6, 20232 yr Author Happened two times since my last update. I limited every Docker Container I have to in total 34 GB of RAM. Should be no problem I think. I also upgraded to Unraid 6.12.6 finally from 6.11.5. Hopefully this helps. I will check it in the next two weeks and update here.
December 14, 20232 yr Author Solution After one day after upgrading to 6.12.6 my server crashed... But after doing the following things everything is running fine: 1. Unistalled all unassigned plugins and reinstalled them (was a hint from here: Link 2. Follow the instructions for the "new" way to fix mtacvlan call traces introduced with 6,12,4 Maybe just number two did the trick. I will come back again when a little bit more time has passed. Hopefully to say everything is still fine. Sorry for using the forum as my personal mind map / notebook thing
January 10, 20242 yr Author To close this, I had no issues anymore at all. Solution was one of the two things in my last post.
