Summary:                    [patch] WARNING[23025]: channel.c:952
__ast_queue_frame: Exceptionally long voice queue length queuing to Local
Description: 
Since upgrading to 1.4 SVN 206273 I see LOTS these errors when paging or
when calls are processed by app_queue.  When I see the messages during a
page I don't hear any paging (my Polycom phones continue to ring but no
paging audio).

I have no idea where the message is coming from how to reproduce, or
collect debug information for this specific issue.  I need help to find
root cause.
I think it could be caused by locking in autoservice since I see this lock
every time I see the warning message
