zerohalo, I only saw one lock resulting in my first bug report note.
Subsequent failures have not resulted in any deadlock but next line in
dial plan fails to execute.

Reverting r165796 fixed incoming IVR failures related to agi in another of
my tickets 14843.  The problem with reverting r165796 for me is that it
removed log notices that implied this problem was related to 14723.  One of
my unpatched (r165796 not reverted) sites reproduced the issues I see
documented in 14723 so imho these issues must be related (at least to my
ticket).

I need to recompile Asterisk without reverting r165796 and with patch from
14723 to see if this fixes at least one site of mine.
What happens if you test patch from 14723 ?
