Can you take a thread dump or three and see what everyone's stuck on?
Hi Mark, Chris, and all the gurus,
I haven't applied this change yet, but something good is happening: Right
now, my Tomcat installation is running fine!
So given that I havent made any changes to my code, I guess my problem is
that sometimes when I stop my website, something goes wrong and not a

Ok, I will do that now!
I have taken another snapshot of the JVM a few minutes ago. Now I also see
that 160MB are being used by org.apache.jasper.runtime.BodyContextImpl.
This contains images of my DYNAMIC pages!

I'm using Yourkit, and this this what I see. The most RAM is used by byte

Hi Mark,
Besides using Tomcat to serve my app (which itself serves about 600,000
diferent URLs), I also use it to serve static pages (HTML pages stored in
the hard disk).
I don't know if Tomcat is caching my dinamically generated pages (maybe it
is), but for now I would love to stop the cache tha

I used a profiler (www.yourkit.com) and took a snapshot of all the objects

Hi
I am running Tomcat 6.0.29 with JDK 1.6.0_22 on Windows XP.
I changed server.xml as below.
Great advice, thanks
I'm using it right now, and I'm also using www.yourkit.com as a trial.
My problem is in the "Tenured/Gen" area. There is where most of the RAM is
getting used. Now I need to fin out what "Tenured/Gen" is about
