Hi Experts,
I know that if you Google 'Tomcat Tuning' you will get some hits (ex.
https://www.mulesoft.com/tcat/tomcat-performance) but I would like to see if
we can have a discussion of best practices for Tomcat tuning from the group of
experts here. Is there an updated top

There are several things you can do:
1) Use a newer JVM.
Tomcat : 5.0.28
Java : 1.4.2 SR8
Apache : 2.2.4
Mod_jk : 1.2.25
Hi everybody,

I agree with Mark, two of those look like coming from the Java 2D
disposer thread, and the other two - as you already observed - come from
OutOfMemory related to growableArray. A quick look into the bug database
shows, that both areas unfortunately seem to be notorious for JVM
crashes. There se

I have put a few online at http://flof.dk/~jbn/hs_err/ - now that I
look at it two of them are OutOfMemory-errors. I newer had those with
Java5, but Sun has accepted a bugreport about it, and we are

No, sorry I misread you mail telling us that you upgraded from 1.5.0_09.
Java 6 should be OK, there is a 1.6.0_01 out for a couple of weeks now.
Still interested in your hotspot error files next week.

Yes, I'm quite sure the hardware is solid.
Actually I'm running
Give us a look at your hotspot error files.
Do they look very close to each other, or do they show very different
stacks as the reason for the crash?
If double free is really the reason it won't be caused by a pure Java

Hi
I'm running Tomcat 6.0.13 on Sun Java6 and Linux. I upgraded from

I experience random crashes of the JVM on a daily basis. It simply
