Microsoft IIS Error - Not enough storage is available to complete this operation

I am running a third party application on Windows Server 2003 and IIS. Requests to specific pages (which process a lot of data) fails with this error:

Error: 
Not enough storage is available to complete this operation. 
Number: 
0x8007000E

This is most likely an issue with the software itself and I already know it should be fixed at code level, but this is up to this third party.

What I am looking for is a way of alleviating this issue by configuring IIS properly (for example: increase buffer and memory allocated for applications). I can easily upgrade the server memory if required.

Any help is welcome! Thanks!
