techystreamer Posted January 31 Share Posted January 31 Not sure where to look further. I have seen the ram usage increase to system instability after zfs rises then falls. I see the zfs rise to max, then the ram increases in small increments after each zfs 100% rise and fall. Once some of the docker apps are started. I have attached a diagnostics file. tower-diagnostics-20240131-0751.zip Quote Link to comment

The instability is almost certainly unrelated, I see on the log some possible AMD GPU issues, also some SMB related call traces. Quote Link to comment

But yesterday I noticed that the rise in ram continuation happens after it hits 100%, it then drops from 100, then rises again to 100, then the ram incremently rises abit. This continues until the ram is maxed and system instability. I have used zfs for about 4 months without issue and understand zfs uses 100%. Whats unusual to me is that it seems to transfer to extra ram use in the ram bar, then continue to rise ram until unstable. Quote Link to comment
JorgeB Posted January 31 Share Posted January 31 The ARC size should be fixed, at least it is by default, if the main RAM keeps going there may be something else using it, check the current ARC size in GB: awk '/^size/ { print $1 " " $3 / 1048576 }' < /proc/spl/kstat/zfs/arcstats After you notice the RAM usage increasing check again to see if it's different.

techystreamer Posted January 31 Author Share Posted January 31 It seems to reach the max and stay within the original settings from what I can see from that screenshot. Is there a way to determine from that diagnostics report what could be causing the ram increase problem? Quote Link to comment

Not that I can see, you can try disabling docker and VM services, then enable just the services, test to see if everything is stable, if yes, start enabling the containers and VMs one by one and retest.

techystreamer Posted February 6 Author Share Posted February 6 Found the issue in the rclone mount. It was running up the ram. 1 Quote Link to comment
