[Asterisk-Dev] Memory Leak in Stable?

[Greg Boehnlein]

Hello,
	I have a client that has a fairly small installation (20 SIP 
Phones) that is running Stable. Asterisk appears to be consuming large 
quantities of memory, and growing uncontrollably to the point where after 
about 6 weeks the box starts to swap itself to death. I've been keeping my 
eye on it today, and in the last 12 hours, it has grown by about 8 
megabytes, and there has been no-one in the office placing any calls.

What can I do to debug this? This is a production system, so during 
business hours I can't muck about with it, but after-hours I can pretty 
much do whatever I want to it... I just need some guidance.
