November 10, 2025Nov 10 Hello everyone,I've been having a problem for the past few weeks where my Unraid server simply freezes and is no longer accessible via the web interface or SSH. The Docker containers and VMs are also no longer reachable.The only solution is to restart the server.Unraid Version 7.2.0BR Andre Edited November 10, 2025Nov 10 by MadMax75
November 10, 2025Nov 10 Community Expert Enable the syslog server and post that after a crash, together with the full diagnostics after a reboot.

November 10, 2025Nov 10 Author I will make the adjustment and see if it helps. Thank you very much for the quick help.
November 12, 2025Nov 12 Author Hello, I had the same problem again last night at 0:37. Are there any other ways to troubleshoot the issue?BRAndre syslog-previous
November 12, 2025Nov 12 Community Expert Did you try adding more RAM? Or disabling some things to test?
November 14, 2025Nov 14 Author Hello,unfortunately, the HP Microserver Gen.8 cannot handle any additional memory. I have implemented the adjustments you suggested.
