What does that mean?
There’s a new check in the active monitoring that will just restart the monitoring thread (not the firewall) if something is wrong with its communications with Asterisk. A couple of people have reported it’s a bit TOO sensitive, but that doesn’t effect firewall itself.
Edit: Firewall 13.0.53.4 has the sensitivity turned down. It’s still possible to false trigger, so if you DO see it happen, I’d love to know.
