This issue can occur when a large amount of data has been collected at the remote Recon site. As an example you may face this issue of the remote Recon site contains 2500 machines and 3 months worth of data for those machines.

This issue is due to a bug in ASP.NET 2.0 Response.TransmitFile function which is resolved in Service Pack 2 for Windows 2003 Server
