I've got a little app...and after few weeks of usage I noticed that one of instances grows to ~50M, since fresh, few-hours old instance usually report ~10M usage, I might be having a leak.

The only datastructures I use are about 10 hashes, they don't grow, and an array for logs, but that gets cleaned every now and then... that would suggest the problem with one with libraries...

How would I go about locating it?
