First time I've seen this in the nearly 2 years that I've been running Unraid, was picked up by the Fix Common Problems and following the advice there I'm posting my diagnostics here for help with this.

Thanks

immich appear to be the issue, check the config or try limiting its RAM

Thanks, I have 32GB of RAM, so surprised that this is an issue considering that Immich recommend 6GB.

 

I have followed the instructions here and limited Immich to have 16GB of RAM and will see how this affects things.

Marking this as solved-
Not had the issue recur, but then again- this only happened the once and months after Immich had been set up.

Will report back if it does.
