Could someone give me a suggestion here? I'm having a problem that looks
a lot like bug  5735 in the Apache Bug Database..
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=5735

Basically, the server will suddenly start launching background threads
until it reaches the maxProcessors parameter of the Connector, and
reject all further requests. The responses in the bug database suggest
using the Coyote connector to fix it. However, I have not had any luck
getting it to work with Ajp13. It appears to me that I have to use the
new Jakarta Redirector for IIS (JK2). Since I have only been able to
find this except as a nightly build (no docs yet) this has been a rather
daunting task.

Also, is it likely that the root cause of this problem could be an
IOException while loading persisted sessions? It seems that we have a
non-serializable object in the session.

My configuration is...
Windows 2000 and IIS using isapi_redirect.dll
Tomcat 4.0.1

 Here is a log segment...
