- Memory Dump Diagnostic
- This feature is only applicable for platforms supported by MDD. Memory Dump Diagnostic analyzes either one single heap dump or analyzes and compares two heap dumps while searching for evidence of a memory leak.
- Memory Leak
- A memory leak is the gradual loss of available computer memory when a program (an application or part of the operating system) repeatedly fails to return memory that it has obtained for temporary use. As a result, the available memory for that application or that part of the operating system becomes exhausted and the program can no longer function. For a program that is frequently opened or called or that runs continuously, even a very small memory leak can eventually cause the program or the system to terminate. A memory leak is the result of a program bug.
