Does Windows have a memory limitation for each program

I have a memory leak in a program we have developed in-house. This leak
eventually [after 20+ hours of running] causes the program to lockup on a
frame grabber function. The PC had 512M of RAM and I setup virtual memory to
be 4G. When the program locks up, Task Manager shows PF usage of around 1.3GB.
Looking for a quick solution, I upgraded to 2G of RAM and left the virtual
memory setting at 4G however this did not change the situation. When the
program locks up, Task Manager still shows PF usage of 1.3GB.
As an experiment, I opened up multiple instances of Internet Explorer with
very large XML files. This allowed me to get the PF usage beyond 1.3 GB. I
then would run the portion of the program that calls the frame grabber
function that normally locks up but it did not lock up. In fact it didn't
lock up until I approched the maximum 4GB. Thus I am wondering if Windows has
a per application memory limit and, if so, is there a way to increase this
limit?
 
Do a Google search on BOOT.INI - there are switches that can be used in
boot.ini they may help you with your problem.
 
The best solution is to talk to the developer, and have him or her fix the
memory leak, increasing memory and pagefile are only bandage to fixes.

Thanks

Fix the leak. It is an in-house program so use the in-house
programmer to plug the leak. Adding more memory won't fix the
problem.
