Mathlink memory hog

Help!  My Mathlink program eats up too much memory!

I am currently having memory problems when trying to run a Mathlink'd C 
program in Mathematica v. 5.  I use Mathlink to call an external C 
program to solve a large sparse matrix.  The problem I am having is that 
according to the Task Manager, the external C code uses a lot of memory 
(mostly virtual memory), >500MB!  Based on the matrix size 73x73, I 
expect the code to use far less memory.

I also searched the net for similar problems.  I found one in which the 
user had to clear a cache directory.  I can't find a cache directory.

How do I keep my Mathlink C program from using so much memory?

Thanks,
Lawrence
