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 believe to have found the issue of the dramatic memory leak. It seems to
be unrelated to CDR or ODBC. It is the Dial function:
I wrote a simple dialplan like this:
exten =>_X.,1,Set(i=100000)
exten =>_X.,n,While($[${i} >= 0])
exten =>_X.,n,Dial(SIP/333333333333 at xx.xx.xx.xx) ; call to cisco fails
immediately
exten =>_X.,n,Set(i=$[${i} - 1])
exten =>_X.,n,EndWhile

I sent 12 calls only to the loop, using two SIP phones, and the memory
keeps growing as it shows this command:
ps auxf --width=200 | grep -v grep | grep usr/sbin/asterisk

Over time, the memory will exhaust and Asterisk will have to be restarted.
