[SR-Users] Segfault on kamailio 5.0.2. Suddenly stops processing traffic, then generates a core when restarting

[Daniel-Constantin Mierla]

Hello,

I answered on the github issue tracker and let's continue there.

In short here: from the provided details, it seems to be the case when
all gateways are inactive, the logs provided having:

Jun 28 01:59:10 kam-1 sbc[12075]: ERROR: <script>: No available gateways
- M=INVITE R=sip:+12345678900 at B.B.B.B:5060 ID=334f3vqDtj

Then a signal 15 (TERM) seems to be received (maybe from a monitoring
app). The segfault happens on shutdown, during modules cleanup.

Cheers,
Daniel
