Summary:                    OPTIONS Messages Flood - Memory Crash
Description: 
Exact revision of Asterisk: Asterisk SVN-branch-1.4-r198665

Checked out from svn using version 1.4:
svn co http://svn.digium.com/svn/asterisk/branches/1.4 asterisk-1.4

Problem: Thousands of OPTIONS messages are sent per minute to particular
devices.

This has happened with a Cisco 7940 with the NAT IP wrongly configured
having an internal IP address that didn't belong to the phone. after it was
corrected to have the router's external IP, the OPTIONS messages stopped.

Asterisk gets to a point where it can't receive any calls because there's
not enough memory left.

It also happened with a Linksys PAP2 that has a public IP, so the
correction above can't be reproduced.
