Load average increase after update

[latimeria]

Hello,
I noticed the load average increased and it's always over 1 after last upgrade to 2.4.1 version; before upgrade it was 0.0x
can you suggest how to check what's going wrong?
Thanks

From witch version you were upgrading to the version 2.4.1? From 2.3.x or 2.4.0 to 2.4.1 or was it from an earlier
version?

What do you think about a fresh and full install? It takes mostly much less time and is then on top of this
more smooth and liquid running. You can fairly backup oyur configuration and reload it then later.

2.4.0 to 2.4.1
But originally it was 2.3 and up to 2.4.0 no problems. I just have openvpn client to connect to PIA VPN
