I have a problem that causes a graph to hang and locks up the agent until is it manually killed. This is a line graph graph that drills down to a report. The problem occurs when one or more of the drill down parameters exceeds a certain number of values.
For e.g
if a parameter NQ_PHYSICIANSPECIALTY = '~COL~ OR ~DER~ OR ~DIA~ OR ~EMR~ OR ~FM~ OR ~DEN~ OR ~SUR~ OR ~GYN~'
the graph runs fine

if the same parameter has an additional value NQ_PHYSICIANSPECIALTY = '~COL~ OR ~DER~ OR ~DIA~ OR ~EMR~ OR ~FM~ OR ~DEN~ OR ~SUR~ OR ~GYN~ OR ~IM~'
the graph hangs
I am able to reproduce the problem using different parameters with both alpha and numeric values.

Upon running traces to isolate the problem, it was found that, the graph gets stuck in the 'Entering DoTheDrill' step in the trc file which generates the hyperlink string. This causes the graph to hang indefinitely.
This only happens when the drill down is on a across column, I have a similar drill down in the header which does not cause any problems.
I have a case open with IBI, but I was wondering if anyone has experienced a similar problem and found a solution.

Thanks

I doubt that this is the problem, but I had a graph with a query string that was too long (for some browsers). I did the following to convert the drill down link to a post from a query string. Give this a try and see if this helps.

	window.addEventListener('load', 'changeAllA', false);

Hope this helps

Thanks for the tip. I'll give it a whirl!
