Summary:                    Memory leak in Asterisk 1.4 and Trunk
Description: 
Both versions of Asterisk have a huge memory leak. I thought that it was
Trunk only and ported my app to 1.4. After 1 day and 17 hours the memory
has gone up 1.2 GB. I only have 300 open calls. My machine is open for
inspection. I am not using "malloc debug" and "don't optimize", for
performance reasons,but I will restart tonight the server. if somebody
wants to suggest any diagnostic technique, please let me know before I
restart.

I think that I found a probable cause for the memory growth. I have two
boxes, identical dialplan, version, etc. In one of them I type "sip show
channels" and I have 60 active channels. In the one where the memory goes
crazy I do the same and I get: 
7.110.179.253   207.2.123.  44938D3E-7A  00102/00102  0x0 (nothing)    No

5552 active SIP channels

Please notice the "(d)" in almost every line. It does not happen in the
first box. In the second box, with the 5552 active channels, I have only 9
active calls, while in the first one I have 30 open calls.

The second box receives calls only from a Cisco 7301, while the other one
receives calls from switches unknown. Maybe something on the SIP interop is
not understanding the Cisco dialogs and this the calls never close. Both
boxes generate CDR's successfully.
