Intermittent Crystal Reports error “The request could not be submitted for background processing.”

Question

We are running Crystal Reports on a Windows Server 2008 with .NET framework 3.5 SP1.

I have seen many causes of the general error \"The request could not be submitted

Answer 1

Is there a chance the report object is leaked in the server's memory? I ran into a similar case where the report object was being stored into a Session object, so the report didn't need to get reloaded as the user navigated between pages. However, when the user was done with the report, the object remained in the Session, and wasn't cleaned up properly when the Session was destroyed by the server. I had to add a bit of code in the Session_End event in global.asax to find the report object and call the dispose method on it.

The fact that this appears intermittently but then affects all reports for a matter of 10 minutes makes me think it could be session-related. In my situation the server reached a limit on the number of reports that could be created on the server (in memory) because they weren't being released. The symptoms were similar to yours.

Hope this helps!
