The problem is if I try running a report multiple times that causes an error (database connection problem, stored procedure problem, etc.) and run a report with no errors that was previously ran, the report hangs-up and all of the reports hangs-up.
What does Oracle do with this? Why are the other reports that was previosly run without errors get affected? Does Oracle Report Service contains cache that stores the errors that occured and if the cache is full it hangs-up?
