Server locking up


Recommended Posts

Hello, I've been having a problem with my server lately. At random times, it seems like, the System Status (on the Dashboard) will show my CPU usage on all cores at 100% and memory at 100% with my dockers being unresponsive. When i look at the system stats with Dynamix System Stats plugin, these appear to be normal though (<10% CPU usage, ~30% Memory usage). Rebooting the server brings everything back to normal, but this is the third time this has happened. Fix Common Problems also did not show any errors after rebooting.


Currently running 6.5.2 (planning on updating to 6.5.3 tomorrow), attached diagnostics taken before rebooting.


System specs are:

Ryzen 5 2400G

Gigabyte GA-AB350M Gaming 3

2.4GB DDR4-3200

Samsung 860 EVO 250GB (cache)

5x4TB Seagate Ironwolf NAS HDD


Any ideas on what might be happening? Thanks!

Thanks, I researched that and found a possible solution for OOM errors using Tips and Tweaks to set "Disk Cache 'vm.dirty_background_ratio' (%)" to 1% and "Disk Cache 'vm.dirty_ratio' (%)" to 2%. I also went ahead and upgraded unRAID to 6.5.3 this morning. Anything else I should keep an eye out for?
