Normal calling (in and out) continues to work fine while this problem is 
being seen.  We're not trunked, though -- each call sets up and tears 
down the connection.

Just finished some preliminary testing on the same Asterisk on a 32-bit 
(instead of 64-bit) machine and the problem is not appearing.  I'm 
reluctant to stamp this as the solution right now, since the test 
machine doesn't have any SIP peers at all (that's the only difference in 
the production and test beds), but am still hopeful.  An i686 Asterisk 
installation on the production server should confirm or deny the theory 
that the problem was purely for Asterisk x64.  Will post once we know 
more.
