I have what appears to be a strange issue. I'm using Visual Studio 2005 ASP.NET/C# and have a problem running a Crystal Report in my web application. 75% of the time the Crystal Report runs fine, but there are times when the Crystal Report won't appear, and the page is blank where the Crystal Viewer control is. The dataset used for the report is populated. This issue appears to happen at times when the site has many hits. Is there any limitation to the number of concurrent users that can run a Crystal Report or a limitation on the number of Crystal Reports that can be run per day. We do not have a separate Crystal Report server. Any tips or help would be appreciated.
