Summary:                    SIP Channels Hang - Last Message: Rx BYE - Need
Destroy: 2
Description: 
I have a bunch of servers running 1.4.21.2.  They are all, on occassion,
getting stuck SIP channels.  Nothing shows up in "core show channels", but
the lingering culprits continue to show up in "sip show channels" until a
restart of asterisk.  The thing they all have in common is that the last
message received was a BYE, and they all have their "Need Destroy" flag set
to 2.  Here are some basic outputs, nothing is crashing so I have no core
dumps, it's a production system so I don't have SIP debugging enabled.  It
seems to only happen in roughly 1 in 5000 calls (estimate)
