I suggest removing all of the bundled web apps (in the webapps folder),
including root, manager and host-manager.
Also, upgrade your JVM to the latest 1.5.x version, which I think is 1.5.15 or
something like that.
Finally, scan your app/system for vulnerabilities with something like these:

What version of Tomcat are you using?
What version of the JVM?
What version of Windows?
Are you up to date on your Windows patches?

Do you monitor your tomcat server(s) for memory and CPU use? I'd get some
baseline measurements and then incrementally increase your maxKeepAliveRequests
value until your problem goes away, all the while making sure you don't have
memory or CPU issues.

Other techniques (access logs, jmeter, etc) should point you in the right
direction but you'll need to do soem more work to figure out exactly where the
bottleneck(s) is(are).

The only thing we found when going from 6.0.16 to 6.0.18 was an issue with some
of our JSP's. The fix is described by "jroller" here:

Try using jconsole.exe (it is part of the Sun JDK) to review memory and thread
usage of your JVM. That should help you narrow down where the issue is. One key
thing to look at with Jconsole is the heap memory used figure. You are setting
your -Xmx, but how much of it are you actually using? Heap

Unfortunately, that doesn't help me with my particular issue. I have a memory

I think you need to add one more line to your CATALINA_OPTS statement:

If that does not help you, I'd try using port 6969 (the default) instead of

troubleshooting process. You could

Yes, that's the way we do it. We use WSUS for Windows patch management, and
