Hello,

I experience random segfault crashes on Asterisk 13 setup with pjsip. Crashes happen for no apparent reason, it can be twice a day, can be once in 2 weeks. I have 2 servers with the same configuration and they both segfault from time to time. I can't reproduce this crash and don't know what is the reason.
I created a topic on Asterisk community and was advised to update my version since there is some issue with PJSIP using TCP protocol and if that won't help then i need to submit issue here.
