Summary:                    core show channels becomes unresponsive - precursor
to deadlock
Description: 
After some period of time, core show channels will yield output, but not
give a final channel count at the end. After that, the console simply hangs
with no further output or commands possible. However, asterisk does
continue to process calls successfully for some period of time after that
before completely deadlocking (if you exit then bring up a new console you
will see output again). 

I suspect this may be a continuation of bug 11080 in some form, but it's
not completely clear to me. I should also note that we are testing file's
patch for 11687, but this didn't appear to be related as far as I could
tell. 

output of core show locks, and the info dump from ast_grab_core attached.

I am experiencing the same issue on my Asterisk 1.4.17 and another server
at a customer site running Asterisk 1.4.15.  They will run fine for a day
or two and then we have people getting fast busy on incoming calls to the
PRI and can't make outgoing calls.  I do a core show channels and I'll
always see just one channel that shows up but isn't really active, because
the phones don't display a connection and I have to restart Asterisk as a
service for it to return to working order.  I spoke with my cousin and he
has the same issues on his Asterisk 1.4 loads.  I never had this issue with
1.2.18 before upgrading to 1.4.17.
