Description:Asterisk hangs the whole system (requiring a hard boot) when using IAX protocol. The IAX client used is idefisk. There can be other reason, as it has also hanged when using SIP (ATA 186).

I got a core one time (attached). I do not get a core always.

I used gdb with bt and bt full. (Output included.)


****** STEPS TO REPRODUCE ******

I am making an IVR, using extensions in extensions.conf. to listen to and test IVR I used idefisk on my PC, and during the call, the system hanged. This has happened many times, and the system has also hanged when listening to IVR using ATA 186 (SIP).

****** ADDITIONAL INFORMATION ******

Core was generated by `asterisk -T -p -vvvg -c'.
Program terminated with signal 11, Segmentation fault.

Please turn off the realtime flag (-p) and try again.

It does not seem to hang now, as I use IAX.

Let me test it for 2-3 days, and then I'll update this ticket.

But why does the Real Time option hangs the system ? For production enviorment, it seems a good option, because then the PBX gets top priority.

There are any number of reasons why this could be.  The real answer is that you should not be using the realtime priority unless you really know what you're doing and understand all the implications of doing so.
