Channels getting stuck open

We have an this issue where channels do not close. We are getting autodestruct messages in the asterisk log files.

It happens every few days, a reboot of the server every night seems to prevent the issue from happening.

We took a core dump when it happened and here are the text files it generated.

We are running:

Asterisk Version: 13.23.1
PBX Firmware: 10.13.66-22

What is the best way to diagnose why these channels are staying open? Does the core dump have the information required to figure out?

I have the same problem,But I have not solved it yet. My reply at is(You can also post it to
The autodestruct message is normally a dialplan error (excessive processing in hangup handler/h extension).
However combined it could be a deadlock, see [ ]
