Hey all,

I currently have a problem with procserv.
I'm using the latest commit from github compilied on Raspbian OS bullseye.

I used manage-procs to create a service but the service gets stopped

every now and then.

The actual runtime seems to be quite arbitrary. Sometimes a few secs

sometimes several hours.

The log output does not really contain any helpfull information.
Any idea what could causing procserv to shut down?

CPU and RAM usage are way below 10% when the IOC is running.

Cheers,
Florian
