Our application, mostly written in classic ASP is leaking memory. Virtual bytes for the w3wp process builds up to about 2 gb withing a couple of hours and then the app pool is recycling, ending all of our user sessions. Eventlog shows an ASP out of memory
OS is win 2003, and server has 2 gb of memory.
I've fetched some debugdiag memory leak reports, but it's not obvious what's causing the leak. Here's some parts of the report that might give some hints. But I don't know where to look next.

Caught another memory leak-report later on that points at the same source: oleaut32.dll. It seems to have leaked 50 mb of memory in 30 minutes. Also mfc42.dll has leaked 25 mb during the same period. From the report:
(a known Windows memory manager) is responsible for 52,39 MBytes worth of outstanding allocations. These allocations appear to have originated from the following module(s) and function(s):
is responsible for 24,73 MBytes worth of outstanding allocations. The following are the top 2 memory consuming functions:
new+15: 24,73 MBytes worth of outstanding allocations.
