This is a very common error in Crystal Report when its give this following message.

"The maximum report processing jobs limit configured by your system administrator has been reached."

I have been read about its on lot forums and new groups. Its actually means that Crystal Report print job limit has been reached and you should handle this problem by increasing the job limit in the registry. The basic reason of this problem is Garbag Collector (GC) cannot clear the reference of report document in their collection process its only clear report viewer.

HKEY_LOCAL_MACHINE\SOFTWARE\CRYSTAL DECISIONS\10.0\REPORT APPLICATION SERVER\SERVER\PrintJobLimit

Yesterday we also facing this problem in our application and after lot of discussion in the team we find out a good solution of this problem in the form following factory class because we not facing this problem in whole application.

You can use this ReportFactory class for creating ReportClass object and don’t need to call explicitly dispose method on the page because ReportFactory class will automatically dispose it when count reach to 75.
