charts won't display consistently

Last Modified: 2012-09-11
I am using the ASP.NET chart control in my app.  In development mode, it works fine.  When I deploye it to my production site, the image displays as an X (missing image).  If I try over and over, it seems to display about half of the time.  The chart is generated through code.  I have a number of these, and they all behave the same.

I know this is not a lot to go on, but am curious if a setting might be needed.  I have the same entries in my web.config (dev and production).  Tried both File and Session based.  They behave the same.

      <add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" />

      <add key="ChartImageHandler" value="storage=session;deleteAfterServicing=true;timeout=20;" />
