Hi everyone,
Have been running truenas scale for some months now, always no issue but now I was getting performance issues when accessing data, so had a look at the memory dashboard and to my surprise, services was eating up 50 Gb of ram.
So I’m running:
-
One VM running nixos, assigned statically 16gb of ram (in the screenshot above, I had just turned that VM off to see if that was the issue)
-
SMB & NFS, usually with no load except in the evenings when I’m streaming video - I turned that off as well to see if it would bring memory usage down, but no effect
-
1 application: tailscale. Turned that off and also unset the application pool to turn off application service but no change.
Went into htop, I see a lot of middlewared processes
Tried service middlewared restart, even just stopped it, but no change in memory.
Anything else I can try? After a reboot, the services ram drops to normal usage again, but it creeps up over a few days until it reaches around 58-59 gbs, only leaving 1-2 gb of ram for my ARC cache…
