We have a new application that we are moving into production on a<BR>clustered, Win2K web server running IIS 5.0 and Application Center. Our database is SQL Server 2000 running on two clustered, Win2K servers. The application was built using Visual Studio 6, SP5 and it uses Design-Time controls and Data Environment recordsets.<BR><BR>We performed a concurrency test with 20 people clicking a button on one of the web pages that would cause data to be written to the database. The application bombed on everyone's PC. Many people just got a spinning globe (for more than 5 minutes). Most people got a "800A01FB - Microsoft JScript runtime exception" or "ASP 0240 - ScriptEngine threw exception 'C0000005' in IActiveScript::SetScriptSite()". All of the errors point to code generated for the Design-time controls or the Scripting object. The event logs on the web servers show the 'C0000005'<BR>exceptions and then it shows the Active Server Page service restarting.<BR><BR>The application works fine with 3-5 people. We cannot find any specific information that would help solve these problems on MSDN, Premier Online or other web sites. Does anyone have any suggestions?
