I'm using SQL Server 2000 Reporting Services. I want to create a curve using
chart for a series of data.
If the number of points (x axis) is small (less than 800), the curve is
displayed correctly.
But if the number of points is more than 800, the curve cannot come out,
after about 1 minute, in the "Event Viewer" of the server, I find a system
warning:
"A process serving application pool 'DefaultAppPool' suffered a fatal
communication error with the World Wide Web Publishing Service. The process
id was '22656'. The data field contains the error number(8007006d). "

Anyone could give me a solution to fix it? Thanks
