March 17, 20251 yr I received an Out of Memory Error in my Fix Common Problems plugin. I've tried to diagnose the culprit but can't seem to find it. Where should I be looking? Dashboard shows 27% RAM Usage of a 64GB system, with ~7G going to Docker, ~7G going to ZFS and ~2.5G going to system. I did make the following changes over the weekend: 1. Changed my CACHE and DATA pools (all NVME / SSD drives) from BTRFS to ZFS. 2. Updated the BIOS on my Motherboard (MSI PRO Z690-A) to the latest in prep for a new CPU install. 3. Ran the 'GIMPS' project from CLI >> the Mersenne Prime Number Search but killed it off after some use and only run when I can monitor it. Diagnostics attached. Any help (along with what / where you examined your finding in the Diagnostics) are appreciated! vault-diagnostics-20250317-0935.zip
March 17, 20251 yr Author I'm also wondering if this error is being given because when I was running a stress test yesterday the test suddenly stopped and the process was killed (likely because it was out of memory) and now I'm being alerted because of that previous event?
March 17, 20251 yr Community Expert Solution Yep, mprime ran it OOM - FCP will warn you about it until you reboot and clear the log

That would do it, the plugin just checks in the syslog whether any out of memory condition was logged since boot.
March 17, 20251 yr Author @Michael_P I was able to find it using grep -r "prime" in the folder -- it's right in front of me in the syslog. Thanks again!
