Need to profile node process. i\'ve some memory leaks in production, after some days of running node process.
i\'ve tried node-inspector + v8, but it doesn\'t work,
I've found node-memwatch useful.
The downside is you have to embed it in your application and have a bit of code for it, but it's useful for checking the heap at various places to see how much it changed after you did something.
You can try to use look module. It based on nodetime but works locally.
