Hi Michael, I did some googling and found this fairly recent Asterisk issue ...
app_queue: Crash when handling hangup with incomplete data https://issues.asterisk.org/jira/browse/ASTERISK-27166 which was closed and merged with ... app_queue: Crash when hanging up with realtime queues https://issues.asterisk.org/jira/browse/ASTERISK-27006 At the end of ASTERISK-27006 "Niklas Larsson" offers a patch that solves it for him, though not a solution. >From what I can tell, this app_queue segfault issue only applies to Asterisk >13, not Asterisk 11. Michael, are you using Asterisk 13 ?
