Summary:                    Huge memory consumption after few hours of load
Description: 
I'm doing load tests on Asterisk 1.6.1.5 and after few hours of load, it
takes 80% of ram (6GB installed), so it becomes unable to fork itself (when
using System() dialplan app), and creating core dump takes an hour. Core
dumps are in size of 9 Gigabytes.

Memory summary doesn't show anytingh of much usage:

80469516 bytes allocated (8800 in caches) in 71421 allocations

while top shows:

Mem:   6055876k total,  6009316k used,    46560k free,    19220k buffers
Swap:  4096564k total,  4096548k used,       16k free,   249980k cached

Not really. I have bunch of realtime dialplans, queues, local channels, and
I'm generating calls that do some random actions, send random DTMFs, do
chanspy, log in and out to queue. 

This is actual simulation of production system, so it's huge and linked
with lots of external stuff.

I would like to find out some way how I can debug this, as "memory show
summary"/"allocations" doesn't really show anything meaningless.
