Server.Execute against same page hangs ASP.NET

[Chuck Haeberle]

We have a page which sends a copy of itself via email to customers. To
enable this, the page calls Server.Execute on itself into a text stream and
strips its own output down to HTML presentable to the customer.

In our Test environment (but not our DEV or Local envs) we are experience an
ASP.NET lockup. The WHOLE asp.net architecture freezes, and we must reboot
the server before any of our other ASP.NET apps will work.

This is a sample of the code which appears to be the culprit. We commented
out the Server.Execute and substituted some junk text to build sbText and the
code worked fine on our test environment again.

-- Locks server
StringBuilder sb = new StringBuilder();
sb.Append(base.AppRoot).Append("/ER/OOWLetter.aspx?ERNumber=");
sb.Append(erNumber);
System.IO.TextWriter textwriter = new System.IO.StringWriter();
StringBuilder sbText = new StringBuilder(textwriter.ToString());
Server.Execute(sb.ToString(), textwriter);

Is there any known issue with Server.Execute on itself?

I expect it would just cause a recursive request of the page requesting
server.execute - and hang your server?

It shouldn't, but I'll look into it.

The call to Server.Execute occurs only within a postback when a button on
the page is pushed to generate the email. As I said, this poses no problem
whatsoever on our local machines (5 developers) or on our development server
environment. Only in our Test env is there an issue.
