[Asterisk-Dev] Suspected memory leak in 1.0.9

[Thralling Penguin LLC]

A suggestion that would help is a Cron script that captures the output of 'show memory summary' every 10 minutes.

I actually have a Python script that does this, parses it to a "database" format and uses a PHP graphing class to chart each part... This gives a GREAT visual clue as to what's leaking...
