I have a server (W2K SP4, and XML3 SP9) with about 100 simultaneous users,
that requests information to varius web services (local and remote).
It has been working fine for years, but in the last months I get frequent
timeout errors. The ASP requested stalls, and after the configured script
timeout it crashes.

I have debuged my pages and found that it can crash in different places
using serverxmlhttp object, I have found a frequent timeout loading an ASP
page that returns a static XSLT only changing the sort attribute, setting it
to the received parameter if any. I doesn't connect to any external source.

This is a sample of my http calls:
set objHTTP= CreateObject("Msxml2.serverXMLHTTP")
objHTTP.Open "POST", "http://local.ws/bin/getXslt.asp", false
objHTTP.Send  <<<<< I get here the timeout

Could it be a problem with ServerXMLHTTP, DOM, IIS? 100 simultaneous
connections is too much for one server (2GB RAM, core duo 1.6GHz)? Could the
different serverxmlhttp requests block each other?
