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 10 list
Tomcat : 5.0.28
Java : 1.4.2 SR8
Apache : 2.2.4
Mod_jk : 1.2.25
Hi everybody,
is there any doc. about the tuning of tomcat ?
Best Regards

There are several things you can do:
1) Use a newer JVM.
2) Use a newer version of Tomcat.

The reason for that is performance tuning depends almost entirely on the

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

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.

Hi
I'm running Tomcat 6.0.13 on Sun Java6 and Linux. I upgraded from
Tomcat 5.5.17 and Java5 update 9 a couple of weeks ago.
I experience random crashes of the JVM on a daily basis. It simply
fails with segmentation faults, double frees and similar. Are any of
you experiencing similar problems?

Do they look very close to each other, or do they show very different
stacks as the reason for the crash?
