[asterisk-users] channel.c:780 channel_find_locked: Avoided deadlock

[Michael Mendoza]

Hi All.

I have many days reading and research about asterisk and vicidial. I thing
this issue is about asterisk and doesnt about vicidial. Isn't it?

I have a problem with theses application (I already ask for help in vicidial
forums), but I can not fix it.

I have debian 5 with asterisk 1.2.24 and vicidial 2.0.4. This server has a
IAX tunnel with another asterisk server B which connect to the carries... I
can call using eyebeam directly and I can start the call.

Asterisk is running ok, but when I tried to do a call with vicidial my phone
ring but when I pick up the phone, the CLI  show:

WARNING[16629]: channel.c:780 channel_find_locked: Avoided deadlock.

And the call is active, I can talk and listen to my partner :s

But reseraching a lot in google, that warning sometimes doesnt afect the
call. in some cases the call is going and I maybe that messages IS AFTER
hung up.

What can be wrong here  ? :s

This is part of /var/log/asterisk/messages:

and this is the log CLI:

In the other asterisk server (B whiche connect with the carries) I get this:
