Asterisk is frequently segfaulting (several times per week) in __ast_queue_frame at at channel.c:1450.
This is a fairly busy call routing server with up to 120 calls at peak times. Calls come in on a SIP channel and are routed straight back out on another SIP channel. directmedia=yes.
There are about eleven lines of dialplan for each call:
The problem does not appear to be load related. The segfault has happened with only 26 calls in progress.
The segfault has also happened after only 30 minutes of uptime and then not again for a few days.
We have seen the problem on three different VM's.
I have a feeling that the problem is only happening with calls from one source SIP trunk but I have been unable to prove this.
I have attached a backtrace. Please let me know if any further information is required.
