From time to time my Asterisk (18.104.22.168 and 11.2.1) all of a sudden stops accepting SIP requests - existing calls go on, but the SIP requests of new calls will time out. Doing a “module reload” does not help, the only thing that helps is a complete restart. The log file (log level debug) does not show any error.
The error occurs once every 2-10 days.
The problems started after updating from 1.8.17 to 22.214.171.124. I’ve tried updating to 11.2.1 but that has not helped either.
Any tips on what could be causing this or how to troubleshoot?
