October 3, 20232 yr Started getting this issue raised in Fix Common Problems, and my server keeps becoming unreachable. If I IPMI in, it shows the normal login on the command line while its unresponsive but cant get to the web ui or anything running on it. hulk-diagnostics-20231003-1458.zip
October 3, 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/
October 3, 20232 yr Author Seems to be happening pretty much daily now. Ill try adjusting the Ram as suggested
October 9, 20232 yr Author I ended up doubling the amount of RAM in the server as it was cheap, but I'm still getting the error and it's causing the server to become unavailable every night now around 4AM. I have removed some dockers and turned off everything I don't see as mission critical. I think this might have started happening around when I updated to 6.12.4.

October 9, 20232 yr Community Expert You need to try and find out what is causing the memory leak, you create the small script below with the user scripts plugin and schedule it to run hourly, it will output the memory stats to the syslog, disable all services, confirm memory usage is not increasing, if yes start enabling things one by one and re-check after 1H. #!/bin/bash free -h |& logger &

October 9, 20232 yr hi, I keep getting that error message too now all of a sudden. Does your RAM stat also look like this?
