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.

I think we need to come up with some teories before we can attack this.
Does this happen when you only run SIP 2 SIP and NO H.323 too? Just to put
H.323 out of the scope.

Since SIP doesn't open UDP ports, session timers must somehow affect the
RTP layer. That's my only idea. We will have to ask other developers if
they can come up with something clever on this or have time to log in.
