Summary:                    Asterisk 1.6.2 beta 4 has UDP socket leak when using
Sip Timers
Description: 
With Sip Timers enabled, the linux count goes through the roof after a a
few hours. With only 30 calls the count gets to 5000+, while with Sip
Timers disabled (session-timers=refuse) it stays close to 100. This
problems takes down the entire Linux OS after a day or so, and also makes
Asterisk increasingly slow and CPU consuming. The command 'sip show
channels' shows only the right amount of dialogs, so this is not related to
an existing bug that deals with a similar, in appearance, problem.

My H323 traffic is minimal. I dispute your idea that SIP does not open UDP
ports, since it is all it does. I mean, 100% of SIP goes over UDP, and it
is definitely the SIP timers because if I switch them off, the problem
stops.
