Description:Hi,

Asterisk randomly crashes with segfault:
{quote}
segfault at 10 ip 00007f954fc2ea0b sp 00007f9528698a60 error 4 in app_queue.so[7f954fc13000+38000]
{quote}

I could not reproduce it effectively, the agents only notice that calls are getting dropped (due to the crash and subsequent restart). To me it looks like it happens only if a call is terminated.

Attached are the files taken by ast_coredumper.
Please let me know if I can provide any additional information.

If possible can you also attach a debug log? Please follow the instructions on [collecting debug information|https://wiki.asterisk.org/wiki/display/AST/Collecting+Debug+Information] from Asterisk. For expediency, where possible, attach the debug with a '.txt' file extension so that the debug will be usable for further analysis.

Thanks!

Hello,

sorry for the long delay, I was not able to reproduce the crash manually.
Asterisk crashed again yesterday (At 10:10:50ish - Restart happened at 10:10:59).

Please let me know if I can provide any more information.
