Page Termination Crystal 8.5

I am using Crystal Reports 8.5 and connecting to a SQL Server 7.0 database through and OLE DB connection. I am running a stored procedure that returns close to 8 million records. This part works fine. My problem is during the process where the status bar states "Determining Page Count" the report will terminate prior to obtaining the end of the report. For example this morning the report terminated after 18+ hours on page 1755. This is a monthly report that is run and last month it had about 2000+ pages. The report has terminated anywhere from 1350 pages to 1760. There are no error messages. If you click on the button to go to the end of the report it will go to page 1. The page count remains Page 1 of 4,294,967,295 because it never completes pagination. Has anyone else experienced this problem?I found the solution to the problem. There was simply too many calculations going on for crystal to handle. The report was summing/grouping over 8 million records. I was able to move this to the stored procedure and eliminate the summing in crystal. The report runs much faster!!
