Leandro Dardini commented on ASTERISK-26545:
--------------------------------------------

Unfortunately I have not much... just asterisk logs. Servers were quite busy and I didn't find a way to reproduce the crash... it just happen. However asterisk verbose log has some messages I have never seen before... FRACK! 

Both servers crashed in the middle of the day, but the second one (Robert backtrace) started to throw "FRACK" messages even during the night , when no activity was taking place. I have attached both /var/log/asterisk/full messages.

I checked other servers running 13.12.1 and I can find the FRACK messages on each of them (apart from really quiet servers), but no crashes. I noticed FRACK messages were thrown even with asterisk 13.12.0-rc1

If you need me to run a customized version to get more info around the FRACK message or whatever test you may need, I am available.

> I started upgrading servers from 13.2.0 to 13.12.1 and some started to crash for segmentation fault. Function involved seems always sip_send_mwi_to_peer
