> The one Asterisk box crashed yesterday with a segfault. The fault was generated in in "ast_openstream_full" (from backtrace)
> Yesterday was a particular busy day (not the most). This queue could have had up to 300 people waiting in it on for up to 1 hour. 
> Also of interest the core dump was not in /tmp/ but rather in the moh folder (/var/lib/asterisk/moh/..../core.31562). This was no big deal (other than tricky to find), but clearly pointed to the problem being part of moh or some playback sound file issue.
> Last time this happened (about 3 months ago), the exact same thing happened. It was then that i converted all the moh files from .wav to .g729, in an attempt to avoid transcoding (if any). Clearly this didn't help. I see also in this case the "say_periodic_announcement" appear in the bt output - would it help to convert the announcements to .g729 also?
> I know some of the values are "<value optimized out>" but please can you look at this anyway - its really the only issue we have left with Asterisk... Or give me some guidance to get the queues to operate under high load correctly. It does seem the issue is with "ast_openstream_full", just not sure what.
