There could be any number of reasons for your app running out of memory, many of which aren't going to be discovered using task manager, process monitor or performance monitor.

To find out what is truly happening you need to either profile the application using a tool such as Ants Memory Profiler or dig deeper and capture a process dump to analyse in WinDbg + SOS.

Tess Ferrandez has a great series of articles on how to get to the bottom of such problems:

There's also a nice series of tutorials to get you started with ADPlus, WinDBG and SOS:
