[asterisk-bugs] [JIRA] (ASTERISK-27166) segfault at 10 ... error 4 in app_queue.so

Mario Lenis commented on ASTERISK-27166:
----------------------------------------

I've been trying to reproduce the error but it happens randomly. What I see in common is when asterisk crashes, I see a beeperr message (transfer failed), agent hangs up before any agent answers

All transfers are attended using the features.conf setup, 

This is the minimun setup, there are some ODBC functions but since it doesn't show any errors or warnings I think it has no relevace. I appreciate any help and thanks in advance.

>          Issue Type: Bug
>      Security Level: None
>          Components: Applications/app_queue
>    Affects Versions: 13.17.0, 14.6.0
>         Environment: Linux Slackware 14.2
> Kernel 4.4.14
> Intel(R) Xeon(R) CPU E3-1220

> This is the scenario:
> 1. Call enters to a Queue A and is received by Agent A (chan_sip)
> 2. Agent A executes an attended transfer to a Queue B and hangs up before someone answers.
> 3. The trasnfered call is not answered since Queue B has callback agents and none answers.
> 4. The attended transfer fails (beeperr) but the original channel had been optimized.
> 5. Asterisk stops.
> This is the backtrace of the issue.
