             Summary: Crash on Transcoded Audio in PERIODIC_HOOK Function
                 Key: ASTERISK-27050
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27050
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 14.5.0
            Reporter: Joshua Elson
         Attachments: coredump.txt, extensions_crash.conf, pjsip_crash.conf

This is an interesting one. Transcoding an audio file on a periodic hook will almost always cause a crash. If it does not cause a crash, it will peg a core and eventually lock up Asterisk.

Steps are as follows:

The originating endpoint needs to use a higher def codec (confirmed crashing with opus,g722, and speex 16/32)

The dialplan must apply a PERIODIC_HOOK to the originating channel.

Playback a *.wav file on the same channel the HOOK was enabled on.
(Tested this with .sln16/.gsm and things work as expected.)

This usually causes a core dump of asterisk, but occasionally locks up the thread, pegging a core and making asterisk totally unresponsive.

Attaching the stack trace and sample dialplan to generate the issue.
