March 29, 20233 yr After I upgraded to 6.12rc2, i am constantly getting out of memory errors daily. I've got 256GB of ram, running ZFS. It's resulting in me having to restart on a daily basis. Initially I didn't set memory limits on my dockers, but setting memory limits seemed to have improved the situation, but am still getting these out of memory errors. Is it due to ZFS? But I wasn't getting these errors before when on 6.11.5 with the ZFS plugin. Have attached the last 3 diagnostics in case that can help. Any gurus able to assist with some advice? Much appreciated.

March 29, 20233 yr Community Expert Solution Are you using the default ARC size? The problem is usually not just about not enough RAM but more about fragmented RAM, a small swap file on disk might help, you can use the swapfile plugin: https://forums.unraid.net/topic/109342-plugin-swapfile-for-691/
March 29, 20233 yr Author Yes, am using the default ARC size. Would an L2ARC help? Thanks for the swap file plugin, setup the swap file to 4GB for a start. Will continue to monitor. Thanks

I am also having this problem and the only thing that I've changed, other than updating to the latest release, is I swapped 2 drives over to ZFS. And my ZFS memory is constantly 99% full. So as I don't actually have any use for ZFS, I'm going to switch back to xfs. There is some discussion I saw on Reddit about increasing the ZFS memory size if you choose to go that route, if that's your same problem.
