We have a process where we read in a CSV file line by line, do some
processing to the data, and then write it back out another CSV file. These
files can have up to 25,000 records. We originally did the processing in
ASP, and it took about a half hour for 25,000 records. To improve the
performance, we moved the processing code into a VB DLL and 25,000 records
are about 14-15 minutes. When I call the DLL from a VB app, it works fine.

The problem is when we run it from ASP. We can do files up to 15,000
records fine, but with larger files, the process completes and then
restarts. It's as if the ASP page is being refreshed and starts all over.

Does anyone have any ideas what might be causing this? Is it a matter of
just upping the session timeout or something?

Thanks
