I had no crash so far but my endpoints are still losing registration from time to time and after Asterisk restart. I reffer to this part in ASTERISK-26806:

2. If static contacts are used or a bunch of endpoints have registered and asterisk is \[re]started/\[re]loaded there is a significant slowdown within the options code. This actually blocks until it completes, which as the number of registered contacts increases so does the block/wait time. This needs to be fixed as well.

If i manually restart Asterisk - 70% of my dynamic contacts won't go back so i have to reboot phones. Only after reboot my contacts get updated and register again.

> 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. Also all endpoints that were registered before crash don't come back and register, i need to manually reboot/re-register all phones.
> 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.
