March 31, 20242 yr Hi, tonight my Unraid server version 6.12.8 crashed, and I had to hard reset it to get it to work again. Uptime Kuma, running on another system, started to report issues with the first Docker service at around 3:57 AM, continuing until 7:15 AM when every service was unreachable. My backup script which is supposed to run at 6 AM, that would restart all containers, was also not successful. At 8:30 AM I checked the server and saw that the WebUI was not reachable, neither was server reachable via SSH. Only a hard reboot by holding down the power button resolved the issue. I attached the diagnostics from after the reboot, and the syslog file which was written during the crash. Note: Tonight was also the switch to DST, which is why there are no logs from 2 AM to 3 AM. This is what Prometheus recorded tonight: Any idea what caused this crash and how I can avoid a crash like that in the future? gandalf-diagnostics-20240331-0912.zip syslog-2024-03-31.log Edited March 31, 20242 yr by MarcelCliff
March 31, 20242 yr Community Expert Solution Try using something like glances or netdata with persistence to see what container caused that runaway increase in RAM usage. EDIT: Seems it could be immich, try limiting the amount of RAM it's allowed to use Edited March 31, 20242 yr by Kilrah
