Bug#386312: asterisk: deadlocks on channels

[Andres Junge]

Package: asterisk
Version: 1:1.0.7.dfsg.1-2sarge3
Severity: important

After some time of running, some channels begin to lock in a way that is impossible to unlock them.
I have a simple queue with dynamicaly added members, and after a while I begin to see this messages
in the log file:

 DEBUG[4443]: Avoiding initial deadlock for 'SIP/211-778a'

The worst problem is that the Zap channels aren't hangup. But the Telco think they are. So I get this
messages:

 WARNING[4443]: Ring requested on channel 0/3 already in use on span 1.  Hanging up owner.

I'm investigating which is the pattern so I can reproduce the problem 100% of the time.
The problem persists with asterisk.1.2.10 backported from etch.
