Thread 19 has used more CPU time than any other thread (19 minutes), but is
currently idle. The fact that it is a .Net thread implies that your problem
is likely a bug on an ASP.Net page (or a problem w/some .Net code, etc.).
You will need to run IISState while the problem is happening to get a good
log of the issue.
