How to prevent Memory leak & outofmemory error ?

Question

Hello Friends In our C#.NET 2005 Desktop application  in some Crystal reports outofmemory error comes while there are huge records. (used SQLReader & Dataset) Also while user uses whole application for long time it increase commit size memory in Task manager . So how to reduce memory leak in application ? Also we have used IDisposable interface & using statement wherever possible. Also we have released PrivateWorking set memory wherever required. but how to decide exactly from which place memory leaks & how to prevent it ? what could be general cause which leads to memory leak & increase memory usage ? Also is outofmemory error & commit size related to each other ? Plz help Thanks in Advance.

The Out of Memory error is often used for catastrophic errors that are actually not memory errors. So that might be misleading. It could be caused when stack space is too full which could be caused by a recursion problem. Since value types in .Net use stack space it seems possible that too many value types could use up stack space. Note that Windows does not keep memory as clean as we want it to or think it does. If it does not need more meory then it often does not bother to clean up memory. This is done for the purpose of efficiency; it is more efficient to not free memory when the processing is not needed. What is the commited percent ( Memory % Committed Bytes In Use performance counter) value? If the percent value is below 90% then it might not be anything to be concerned about. Also what is the  Memory Available MBytes  counter? What is the  Memory Pages Output/Sec  counter? The problem might be some other memory configuration value such as a buffer size. I am not familiar with Crystal Reports enough to really help with that.
