Hello
On an APU2 I manage with OPNsense 23.1, python3.9 regularly generates high CPU load and subsequently causes the wireguard connections to die. A restart provides relief for a few days in each case.
Where could be the problem there?
Here is the CPU usage of the last 2 weeks
Type
ps awwux| grep python
to see what that python process is doing.
Unfortunately, I have already restarted the box. I look then in about 5 days again. Thanks!
I enabled the new Unbound DNS reporting feature after upgrading to 23.1.
Reporting > Settings > Unbound DNS reporting
I'll try turning that off.

Update: Appears to have resolved the high CPU issue for me after checking a few hours later.

You can try # opnsense-patch 02f44d902 (https://github.com/opnsense/core/commit/02f44d9024f0c9eb53ae2ade83f9ff522218014c) and restart Unbound. This should make a difference in CPU usage with unbound dns reporting enabled.
