After upgrading from 24.7.7 to 24.7.8, the CPU temp of the Proxmox host that OPNsense runs on has increased a fair bit. Has anyone else seen this?
It's still within an acceptable range but it's never been like this for the all the time I've been running it as a VM. There are a couple of other very small containers on the same host, but even when I shut them down the temperature doesn't change. It's also a passively cooled unit so I'd rather it was back to previous temperatures.
A jump of 20°C can most likely be attributed to a higher load by some process. More often than not, such load is caused by a defective RRD database after a reboot - especially if you do not use ZFS as underlying filesystem.
Try checking your process list via 'top' and if there is a CPU-hogging process, you can try to reset the RRD and Netflow databases under Reporting: Settings.
P.S.: I do not see any jump.
Thanks for the advice, I think I found it - when I ran top the only process that looked to be constantly busy was "monit", and when I tried to stop the service nothing happened, either with the menu option or with the diagnostics/services menu. So I tried to kill it through top and still the process would not stop, and even a normal kill failed on the command line. Had to use kill -9 to get it to stop.
I then checked the monit log and it had been repeatedly complaining for a while about a Suricata alert not available, although the last message was over 12hrs ago, which was probably as I stopped using Suricata quite some time ago. I removed the alert, restarted the monit service and so far the CPU temp has gone back down to previous levels.
