Mike,
It's not the fact that the program uses or reserves more than need or that
it keeps everything in memory to make the program run faster that causes the
leak.
The leak is caused by the programmer or the operating system inadvertently
forgetting to free up the memory that was reserved or used by the program.

Subject: [WriteLog] Software Memory Leak
A memory leak occurs when there is a logic bug in an application pgm that
actually uses more memory than needed (bug in the logic) and eventually you
run out of real and virtual memory from the OSystem. Like when a loging
program keeps everything in memory to make access faster.
There was a fix by Microsoft for at least for one leak in Windows NT back
2-3 yrs ago. But apps do their own thing most times. There does not have
to be a cpu loop to create a memory leak by an application, it is usually a
logic pblm trying to keep too much in memory at one time. When I am using
Win2K , I can see exactly what is being used by program with the Windows
Task Manager and all the system tasks.
