Issue
While trying to run a trend summary report for a large amount of data, the web reporter will return an error and no longer provide any reports until a user closes the browser and re-opens.
The error displayed will say "Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same."

Product
Power Monitoring Expert 7.2.x

Environment
Internet Explorer 10, Internet Explorer 11
Trend Summary report
ASP.NET State service is running

Cause
The volume of data in the report is too large. The report will try to render 6 different types of trends and fail once the data set gets too large.

Resolution
In PME 7.2 the only resolution is to change the amount of data in the report. Either reduce the number of source measurements pairs or reduce the date range of the report.
Issue was corrected in PME 8 Summary report pack where the report no longer renders all 6 types of reports and only renders the one report type selected in the report configuration.
