Summary:                    Deadlock in cahn_sip when using IMAP voicemail
Description: 
I have setup asterisk to use imap as voicemail storage. Sometimes (2 times
since the last hours), chan_sip sould be in a deadlock situation requiring
a restart of asterisk.

When it happens, no communication can be done in SIP, thus no phone can be
reached, and no calls can be placed.

Attach a "core show locks" (core_locks.txt) from the 2 lockup this
morning. Also attach is 2 "thread apply all bt" (gdb_thread_20080603.txt
and gdb_thread_20080605.txt)that I catched while asterisk was running in
the debuger while investigating another issue.
