Dear all experts,

I have run into a strange issue - I understand the problem point - But, I can not think of a solution - so I thought I should get some advice.

I have the following built up;

1. An HTML page with a table of around 200 members (table data is regarding member details)
2. On a click of a button - for each member in the table, I need to run 6 crystal reports and then export it out at a location on the server.
3. I need the feedback of whether the reports are run successfully or not after each member processing.

The problem;

As soon as I click the button to run reports, say 200 AJAX async requests are fired up to a web service with an object as argument containing details of the member (used to run the reports).

Crystal reports can only handle 75 concurrent report processing. I have a global variable (in the web service section) which is incremented as soon as a set of reports get fired up and I limit that variable to 2 members at a time - like a throttle limiting simultaneous execution. As soon as the reports have finished processing for a member, I decrease the variable by 1. If the throttle has max out, I continuously re-check the throttle variable and only execute reports when the variable is available.

The problem is, because of the above scenario, the CPU is used kind of 100% (because of crystal reports and also continuously checking for throttle variable) and I can not fire any other ajax requests from the HTML page. I mean I can fire up the ajax requests but I think CPU is not available to process those request.

Can anyone guide on how to achieve what I want?

If you require any further clarification, please ask.

Thanks.

Nayan
