Memory Leaks in my Ruby on Rails Application

My application calls bunch of API's which returns lots of data which are manipulated inside my controller to give various insights (passed onto my view).

The problem is that I have been having memory leaks in my application for which I currently need to restart my application after few number of requests.

Also, I have been caching all of my api calls to improve the performance of my application. Most of my data is stored in form of hashes when returned by the api and this data is manipulated (sort of duplicated using groupby).

I'm using Ruby 1.9 and Rails 3.2. I need to know how can I remove this memory leak from my application.

You can use bundler-leak gem to find memory leaks in your gem dependencies.

You should confirm, that you indeed have a memory leak and not a memory bloat. You can read about ruby GC here

GC.stat[:heap_live_slot] - this one represents the objects which are not cleared after last GC. If this number steadily increases request by request, then you can be sure, that you have a memory leak.

First you can check a list of Ruby gems that have memory leaks first.
