[asterisk-dev] Zaptel channel lock bug?

[Anton]

Hello guys!

I'm experiencing the following behaviour on the 
asterisk-1.2.9.1 - suddently one of the lines (the 
secretary, used most oftenly), connected over the T1 
channel banks hangs (just become silent) - until I restart 
asterisk. That happens once in a few days, so it's 
repeatable. Hangs just one line (very rarely more)
Setup is very basic, no complicated routing, no meetme 
usage. Just plain Zaptel-channelbank PBX.

Jul  3 09:31:45 WARNING[14626]: channel.c:787 
channel_find_locked: Avoided deadlock for '0x822cb08', 10 
retries!

is the only suspicious line I can find in the logs. 

when happens, asterisk does not shutdown itself on "stop 
now" - just silently continues operation - ihave to kill -9 
it.

Does anyone have similar behaviour? Any suggestion what 
types of logs I have to look/swith on to report in more 
detail?

Regards,
Anton.
