Well I am not sure there is a problem to begin with.
Is this a Web site that can be accessed from outside or is it inside of your firewall?
If it is accessible from outside, we'd like to ask you to zip up your project including your data sources and file a support case at our
Support Site. We can then replay it and see what the deal is.
Without either that or having a streaming session to understand how the various scenarios interact in terms of virtual user numbers and the associated datasources it is pretty hard to figure out where the catch is. I think it has to do with the size of your various datasources and the load profile for your test.
