This problem was called "garbage collection" in the previous millenium :-)

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.
