I have 2 servers running Scale and upgraded them both to 24.04 when the beta came out and noticed that slowly over time the Services memory usage would climb from around GiB up to all of the memory available on the machine. I then upgraded both to the RC1 version to see if that helped, but the iss…

If the system is basically vanilla with no apps / VMs running I’d try a clean install first and restoring the configuration, but if that also fails I’d suggest a bug report.

This would be normal if one of your services had a memory leak. Maybe top or something similar can show what’s using all the ram?

That does sound like a memory leak. To troubleshoot it here, the output of top or htop sorted by memory usage would be helpful. Otherwise a bug ticket and debug file. Thanks!

Yes thanks for the replies. Both systems are vanilla with no apps and no VMs. htop shows the top processes as all middlewared: [image] This htop though is the current system state where memory hasn’t climbed back up all the way. It is currently using 8.2 GiB on system one which was rebooted 4 …

If its middleware then that sounds like a legit bug. Can you file a bug ticket (Link up top) and attach a debug file from one of the systems where it is showing signs of that memory leak?

Thanks for your help. I have created a bug ticket and uploaded the debug files. Thanks, Jeff

Those screenshots don’t show a memory leak. The tool you’re running seems to show threads as separate processes.

I’m seeing something similar here. When I reboot my system, a small amount of memory is allocated to ZFS Cache. This would top out to about 50% of my memory on the previous version, but now I’m seeing ZFS Cache consume just about all of it to the point where I’m no longer able to start any VMs. Re…
