Joshua C. Colp commented on ASTERISK-29210:
-------------------------------------------

A platform/usage patterns/CPU can all contribute to exposing an issue that is possible on everything but may not be easily caused on other systems. Disregarding Google Voice as a factor just because it's not happening on other systems is a bad idea for that reason.

> When starting Asterisk in daemon mode, using /usr/sbin/asterisk or /etc/init.d/asterisk start, daemon starts with no errors, but within a few second, ps shows that the daemon has crashed and that the process /usr/sbin/asterisk is no longer present. When started with -g option, produces a core dump. When started with /usr/sbin/safe_asterisk, produces continuous core dumps in /tmp.
> Interestingly, when started in CLI mode in foreground with /usr/sbin/asterisk -cvvvv, so far it has remained stable with no auto-shutdown or no core dump. SIP connection to SIP provider is established and voice calls work. More testing is perhaps needed to see if core dumps can be replicated in foreground.
> /var/log/asterisk/messages does not show any errors/warnings at the point of daemon crash/core dump.
> All testing is currently at halt and rollout to production status is on hold, due to these continuous core dumps.
