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 On 29.06.17 03:37, Joel Serrano wrote: 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. _______________________________________________ Kamailio (SER) - Users Mailing Listsr-users@lists.kamailio.orghttps://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users -- Daniel-Constantin Mierlawww.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio Advanced Training - www.asipto.com Kamailio World Conference - www.kamailioworld.com
