IIS hangs after 300+ PDFs created - AR1 1.1.0.84

We have been experiencing IIS services, more specifically the Web Publishing
service getting hung on an NT4 box after 300+ PDF files were created via our
ASP application.
The web application uses a DLL created using VB6 to export an ADO recordset
to a PDF file.
We noticed that we were experiencing problems [ASP0115 errors, PDF file is
only 1K in size and contains no data except for the PDF file header, etc.]
so we have been rebooting the server about once a week.
After reviewing the log files [DLL creates an ASCII file with info on when
the DLL was instantiated and terminated, what the PDF filename is, date and
time info, etc.] we determined that somewhere after 300 to 400 files are
created we start experiencing connection problems.
After about 10 to 20 failed logins we try to stop/start the IIS services but
always get a memory read error when the Web Publishing service fails to
stop. This necessitates a cold reboot of the server.
Last night, after the 425th PDF file was created, I tried to stop the Web
Publishing service and it failed. The error message state it could not stop
the service in its current state.
My guess there is a memory leak somewhere. We can verify that our component
is terminating because the log files we create contain the termination
message from the class terminate event.
We have since installed the sp4 for AR1 but are experiencing a different
problem now [see Can't have more than 2 connections to IIS with AR v.1.1
sp4].
Any ideas? Anyone?
Thanks
