Hi

My application runs for few hours, There is no increase in any value ( vmsize, memory) of Task Manager. But after few hours i get out of memory errors.

In sysinternals i see that "Virtual Size" is contineously increasing, and when it reach around 2 GB i start getting memory errors.

So what kind of memory leak is that ? How can i demonstrate it with a code ? Is it possible to reproduce same thing with any piece of code where none of the memory value increase but only the Virtual Size in sysinternsl process explorer increase ?

thanks for any suggestions
