Mime Type Header errors!

[EP...@upstate.com]

Hi,

I just moved my Turbine application from one server to another.  The new one
has jdk1.4.1 and tomcat 4.1.24.  My users are complaining of clicking links,
and getting back a "page not found" error.  If they refresh, then it does
hit the page.  I looked into the logs, and found these errors:

It seems to happen when I run Tomcat as a service on windows 2k.  Not
immediatly, but after a while.  If I run it as a console app, then it seems
to work fine.  This is very mystifying and frightening, since the old server
and new server are identical as far as I can tell...
