Jesse Ross commented on ASTERISK-28689:
---------------------------------------

Not sure if this helps, but I looked in 'messages' instead of 'all' - I had verbose(30) instead of verbose(5) there - and found this:

This following happened at the same timestamp as the crash (time that kern.log says the crash happened - 22:45:30) 
but there was a page or so of "res_pjsip/pjsip_distributor.c:" stuff before the asterisk start up log.

It also crashed at 22:38:58:

Also, I got my firewall/fail2ban situation under control so my future log files won't be so messy if you need them.

> Hi,
> We are getting crashes like this randomly:

> It didn't happen at all before but started to do it a couple times a day. Now it is doing it around 20 times per day. But only in the evening for some reason... 
> I've attached the core dump info.
> I upgraded to 13.30 from 13.20 and installed the latest libpri and dahdi but it didn't help.
> Thanks
