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

[Bartosz Jozwiak]

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 ?
