Finding memory leak

Question

I have a web application that I wrote using a lot of different 3rd party components, a CMS and of course my code. For some reason I get out of memory exception.

Answer 1

You mentioned "I've added a space in web.config and suddenly my IIS process started to grow to more than a GB in 30 minutes". In which web.config tag have you appended this space. What part of your code uses it. Is that part of your code unable to handle some exception without causing memory leak. Use PerfView (Dump GC heap) to analyze the dump. This can exactly tell, the object of what kind is taking up this much of memory. In older versions of .net, it would be objects on large object heap (big arrays) or open and mis-handled db connections and files.
