What is the most effective way to determine if a particular app is leaking memory? In other words, what exact steps would you take, extra apps you would use, settings etc and then procedure you'd follow to determine this with some confidence? The OP said LI5 was her cause but not sure how that was determined... I have LI5 and would like to monitor for the same thing... thanks for any feedback or link to a post that details what I should do above and beyond just seeing the avilable RAM (which I know how to turn on in SBS) which doesn't specifically let you know which apps are lowering RAM or leaking it when there are many running in the background.
