Crystal Crashing when many users

Hello,

I am having an issue with the code below:

            try

            {

                crystalReport.Load(rptFilePath);

            }

            catch (Exception ex)

            {

                return("Error Loading Crystal RPT File (" + rptFilePath + "): " + ex.Message);

            }

It works fine usually, but when I get many users trying to run a report at same time I get an Exception:

"Load report failed".

Furthermore once I get this exception it looks like no other users can run reports (as if the report component crashed).

I have to either reboot IIS or wait some time and it looks like the Crystal Component recovers on it's own.

I was warned that by using this free Crystal VS Component, I can only have max of 4 concurrent users calling it at the same time.

Is that the correct number about 4???

So I understand it is giving errors under heavy usage.

But it seems that t is also crashing after the first heavy usage and then no longer works after that.

Is there a way to make it recover without rebooting IIS or waiting a long time?

Thanks,

Yury
