Hi everyone,
since installing the update to 22.4 my virtualized OPNsense consumes much more CPU-Load. It increases from about 5-7% in average now to 25% and more.
Using top on the shell I saw an Python 3.9 processes that consumes every couple of seconds ~99% CPU.
The VM is running on a Proxmox Server (7.2-7) based on an Intel NUC7i5. The vNIC type is VirtIO and the QEMU-Agent is installed.
Any ideas what this Python process is doing in short intervals?
Netflow is disabled.
Thanks in advance!
Stefan
Try ps awwux | grep python at the moment when the process is running. May be a table update, on my system running every minute causing CPU peaks by python.

flowd_aggregate.py is the malefactor!
I re-checked my settings and I found under Reporting/Settings that the option "Enables the RRD graphing backend." was still enabled. After uncheck this option, the Python process wasn't consuming CPU anymore.
Thanks for your help, tiermutter! :)
Cheers,
Stefan
