Summary:                    Asterisk random crashed 4 times one day
Description: 
It is difficult to reproduce the random crashs. But from the CEL events and
crash core time we can guess the crash scenes.

The 1st and 2nd crash occured when a queue finished. These crashs seems
have relationship with CDR. After I set the cdr enabled=no the crash
doesn't occur again.

The 3rd crash occured when a dial-out channel started. The 4th crash is
similar with the 3rd, but the crash core generation time is 10 seconds late
to the channel start event. I guess it occured when the channel was
answered.

This appears to be a channel reference count issue.
