Error Executing child request

Jul 31, 2009 at 8:59 PM

The web part installed as expected and I was able to create a poll.  When I clicked Submit I got an error "Error executing child request for ChartImg.axd."

Any ideas on how to fix this?  Thanks in advance

Do you have multiple web front ends that are load balanced with something other than WNLB? aka - a load balancer that doesn't have "sticky" sessions?


Or, do you have multiple W3WP processes assigned to your app pool(s)?


If yes to either of those, check out this blog post:


Essentially, I'm storing the chart image in memory which may not be accesible if you're hopping servers or processes. You can change it to write the image to the file system instead to make it more available.

I installed the chart

put this to the web config of my site collection <add key="ChartImageHandler" value="Storage=memory;Timeout=20;"  /> also tried the other way around storing the file on my disk

I still get this error "Error executing child request for ChartImg.axd."

Could you help me?
