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?

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:
I use Sun's Visual VM.

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

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?
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:

Since I had a real hard time getting to this website, I'll copy and paste the
article here
Tomcat 6.0.18 includes a
that much memory!

I don't know if this will actually help Mike do what he wants to do. I don't
think he needs to know about Tomcat SSL configuration.
I think we do exactly what Mike wants to do...we have a network load balancer
with SSL accelerator in front of all of our Tomcat instances. All of our

Hello,
I run Tomcat 6.0.x as a service on Windows 2003, using Sun JDK 1.6. I was
trying to use the jstack program, part of the JDK, to get a stack dump from
Tomcat/Java on my server. However, I ran into a problem. First of all, Tomcat
on Windows seems to hide the JVM instance. Java doesn't
Thanks everyone for their suggestions.
Unfortunately, that doesn't help me with my particular issue. I have a memory
leak in one of my apps, and when the system runs out of memory, it stops
responding to new requests. I have a script that will detect this condition and
automatically restart
I think you need to add one more line to your CATALINA_OPTS statement:
-Dcom.sun.management.jmxremote=true
If that does not help you, I'd try using port 6969 (the default) instead of
. It should not matter, but I would at least give it a try as part of the
troubleshooting process. You could
So, do you think Automatic windows patch
management and manual tomcat patch management would ideal as patch releases
from Tomcat is very rare?
Yes, that's the way we do it. We use WSUS for Windows patch management, and
manually upgrade Tomcat as needed. This has not been an issue for us, as
At the bottom of my Tomcat 6.0.16 logging.properties file, I have the following

#org.apache.catalina.session.ManagerBase.level = FINE
