Hello,
when our Asterisk accepted no more calls yesterday with a "Hanging up owner"
message, I also found a "Cause 34" message in the logs,
but there were enough free channels! So I discovered this list and read all the
"Cause 34" messages. I wonder if the "Hanging up
owner" deadlock could be caused by this?
Even if it is not related, we face the "Hanging up owner" problem on different
machines sometimes. It can work two months without
problems, but also happened two times in one week, bringing all channels down.
So a solution would be most appreciated.
Here are the details:
Asterisk 1.4.19.1-BRIstuffed-0.4.0-RC1 on a Debian box.
Digium, Inc. Wildcard TE205P connected to a PRI Telco line (30 channels).
(Im breaking up the log for readability)
SIP 454 tried to dial 0170XXXXXXXX. It is 100% sure that there have been free
channels at that moment.

This seems to me like the "Cause 34 on free channel" problem discussed
elsewhere in this list.
Now it continues, I jump to +201 in the dialplan after the dial command.
Unfortunately there was an error in the dialplan:

Context [s2m-error] was missing the '1' priority :-( --- blame me, if that
causes the following errors, though I doubt it. Here the
"Hanging up owner" hing starts:

I see 102 is AST_CAUSE_RECOVERY_ON_TIMER_EXPIRE. What does this mean?
>From here on the log is full with "Hanging up owner" messages for more than 40

till we restarted Asterisk and the Zaptel drivers. There were 2 incoming (data)
calls,
which got through but which also got hangup with cause 102 and two outgoing
attempts
which got the "Cause 34" error again. Obviously other calls did not come
through.
