We recently upgraded ActiveReports on our ASP.NET intranet site to version 14.2. The WebViewer is used frequently and there are many pages that export reports to pdf.
Since upgrading, the IIS worker process memory usage grows and grows until it eventually restarts.
We aren’t getting any errors testing locally or on a test server but on the production server the following error is showing up frequently in the application event log:
Event code: 3008

In another post, I was told that httphandlers were no longer needed so they were removed from the web.config. Do I need to put them back?
