Hello all,

I just released version 0.6 of heapSpank, an open-source Java memory leak detector.

https://github.com/eostermueller/heapSpank

How long should a stability/longevity test run for? 12 hours? 48?
heapSpank is easy to install and it found my memory leak, below, in just minutes instead of hours.
Would love to have some feedback on how/whether it works for you.

To run, just download the jar file and give it the 'pid' of your java process.
It is a low overhead tool, and relies on data from the JDK's jmap -history command.

Thanks,
--Erik Ostermueller
