Your SIP channel driver was deadlocked. This can happen for a number of 
reasons, but all of them are bad, and need to be fixed.

Depending on the Asterisk version you are running, there may be some 
known situations under which they can occur; as best we can tell, there 
are none left in CVS HEAD related to chan_sip.
