Uncovering and correcting memory issues in managed applications can be difficult. Memory issues manifest themselves in different ways. For example, you may observe your application's memory usage growing unboundedly, eventually resulting in an Out Of Memory (OOM) exception. (Your application may even throw out-of-memory exceptions when there is plenty of physical memory available.) But any one of the following may indicate a possible memory issue:

• An OutOfMemoryException is thrown.
• The process is using too much memory for no obvious reason that you can determine.
• It appears that garbage collection is not cleaning up objects fast enough.
• The managed heap is overly fragmented.
• The application is excessively using the CPU.

This column discusses the investigation process and shows you how to collect the data you need to determine what types of memory issues you are dealing with in your applications. This column does not cover how to actually fix problems you find, but it does give some good insights as to where to start.
