found this reference so far...
Yeah, I found these also. This is really well done but, it is also an hour long.
How to use LeakHunter to solve memory problems.
I found this KB article informative on Leak Hunter.
This is a good article as well.
I used the "way, way back" machine to pull up an archive copy (2007) of the original LeakHunter Best Practice. This version has screen shots that are out of date but the discussion will give you a bit more background on how to use it and the types of results that can be expected. Some details of the agent configuration may also be out of date.
Fortunately, memory leaks are always in fashion!
