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.

In your note about a leak, where you run a loop:

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

You will build up memory while the loop is running, basically
the calling channel, which remains alive to allow the loop to
run, builds up a (big) list of dial_feature structs. But, when
the loop ends and the channel is hung up and freed, so are all 
those dial feature structs. In normal practice, this is not
be a problem.
