I have some more info about my deadlocks...

It usually happens when you have a callwaiting and users are pressing flash button
on ZAP channels.

Here is what I see on CLI

Feb 9 14:48:41 WARNING[4225]: channel.c:787 channel_find_locked: Avoided deadlock for '0x9655d18', 10 retries!

Anyone experience the same problems ?


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
