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@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

Hi all, 

I'm running into a weird situation with our newly deployed Kamailio servers. These servers are only doing SSL offloading and load balancing between another set of servers.

Debian v9.0 + Kamailio v5.0.2 (from kamailio50 repository).

After some time of running, kamailio suddenly stops responding to any request but the proccess is still alive. When we restart the service, a core is generated.

I have opened an issue in GitHub: https://github.com/kamailio/kamailio/issues/1172

I'm attaching the backtrace here too in case anyone can take a look at it, unfortunately I'm lost right now. 

In dmesg I saw:

[138953.744199] kamailio[12052]: segfault at 7efaf32f51b8 ip 00007efcf3b5df69 sp 00007ffe325dc0c0 error 4 in libcrypto.so.1.1[7efcf39f6000+265000]

Thanks, 

Joel.
