[Asterisk-Users] channel.c: Avoided deadlock for '0x91a8b20', 10 retries!

[Bartosz Jozwiak]

Dear users,

Couple of days ago I have updated my * to 1.2.4 with ZAP 1.2.3
Since the upgrade I am having these problems:

Feb  7 16:21:18 WARNING[387] channel.c: Avoided deadlock for '0x91a8b20', 10 
retries!$
Feb  7 16:23:16 WARNING[16176] channel.c: Avoided deadlock for '0x91a8b20', 
10 retries!$
Feb  7 16:23:28 WARNING[16176] channel.c: Avoided deadlock for '0x91a8b20', 
10 retries!$
Feb  7 16:23:36 WARNING[16176] channel.c: Avoided deadlock for '0x91a8b20', 
10 retries!$
Feb  7 16:23:38 WARNING[16176] channel.c: Avoided deadlock for '0x91a8b20', 
10 retries!$
Feb  7 16:23:47 WARNING[16176] channel.c: Avoided deadlock for '0x91a8b20', 
10 retries!$
Feb  7 16:24:41 WARNING[16176] channel.c: Avoided deadlock for '0x91a8b20', 
10 retries!$

It happens on ZAP channels ( I have T1 card with channel bank, and analog 
phones ).
It happens randomly with some ZAP channels. I pick up handset and there is 
no dial tone.
Only way to fix it is to stop and start asterisk.

With previous CVS version from 17th of August of asterisk I've been running 
these problems did not appear.

Could somebody give me some "light" on this ?

thx.

Bartosz
