Summary:                    Local dial with moh causes crash
Description: 
When a call using dial local/ goes into musiconhold, and then the sip
extension initiating this call puts it on hold (more musiconhold) asterisk
enters a "crashed" state. any attempt from CLI to "show channels" will kill
the CLI. manager API slows down to an unusable rate. CPU load remains
normal. Asterisk can not be restarted or shutdown from the cli, soft hangup
is non functional. The only resolve is to "Kill -9" asterisk.

This problem appears to exist in asterisk 1.2.18 and 1.4.17(the versions I
have handy).

This crash can be reproduce with the aid of the following dial plan

exten => 400,1,answer
exten => 400,2,dial(local/401)

exten => 401,1,answer
exten => 401,2,musiconhold()

from a SIP phone dial 400, you hear music. Put the call on hold, about 4
seconds later asterisk has entered the above state.

Please recompile with DONT_OPTIMIZE and DEBUG_THREADS.  Then, when the
above described condition occurs, run 'core show locks' and upload the
resulting output as a text file to this issue.  Also, it would be helpful
if you would first update to 1.4.21.1 or later (possibly SVN 1.4), as the
issue may have already been fixed.
