Summary:                    sip call fails to hang up - asterisk uses 99%
resources
Description: 
After upgrading to 1.8.2 (and also present in 1.8.1.1) asterisk is often
found to be consuming 99% of resources. 
This has been traced to calls which have been hangup by the remote party
but are still show as active (in BYE state) in asterisk.
It does seem to be random but happens so frequently that I can easily
reproduce this state by doing test calls until it happens. I can do any
debugging or tracing that is needed, just point me in the direction of what
is needed.
