python3.9 generates high CPU load and kills Wireguard

[STRUBartacus]

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?

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.
