As noted under more information for this issue I have captured diagnostics prior to rebooting. If you can assist me with figuring out the issue that would be fantastic?

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:

Thanks. so far this is the first time I've ever gotten this error so hopefully it's just an anomally. I may still adda dn start using the swapfile plugin though. That seems like a very useful idea.

Was having problems with server freezing and finally after days of looking and watch videos I found a post and I added /dev/dri to docker configuration and that seems so far that has keep it from freezing, but I got an error message about memory.

So I woke up this morning to the same error. The one thing I noticed that was the same this time and last time was this

Note hoow ZFS is at 100%. The only drives I have as ZFS right now are my cache drives. Rebooting resolved this last weekend. I haven't done the swap file thing yet. Getting ready to reboot again for now.

The ZFS (ARC) is expected to be at or close to 100% in use.

What time is your Plex maintenance scheduled? Try limiting the Plex docker's memory, that will keep it from running away if it encounters a file it doesn't like.

Plex takss are scheduled for 0200

Third week is the charm. Same error as usual along with a new one: /var/log is getting full (currently 79 % used) which I just posted about in the FCP forum per the note in the error message. This weeks diags are attached. 

 

Whatever is causing this (these) issue hasn't otherwise affected the day to day use of my server thus far. So I'm not freaking out about it. But I would like to figure it out before it becomes a bigger issue.

You are still having OOM events, but it appears there's something else filling up the logs, post the output of:

 

du -h /var/log

Did you try limiting Plex's memory in the container settings?

Honestly I got busy with other things and forgot about this. Additionally, I'm not quite sure how I go about limiting Plex's memory in the container settings.

In the container's settings, toggle advanced view and add this into the extra parameters field (whatever amount of RAM you want to limit to, I just use 4G
