Do you have any native code components?
I had a serious problem with OutOfMemoryError: unable to create new
native thread errors too. They pretty much went away when I ditched
the Oracle OCI driver in favor of the thin driver.
BTW, the default linux kernel puts a hard limit of ~1k threads on
closer? Ummm, maybe, but still hideously broken. If you're using
BLOBs from Java, forget both Oracle and PostgreSQL - their JDBC drivers
are horrible. And if you want to lie awake at nights shivering,
desperately trying to clear your mind of a gastly, horrible vision -

We're seeing very uneven loadbalancing in our cluster of four tomcat

have any idea why this might be happening?

100)

FYI, no it doesn't, it just causes the (Sun, at least) JVM to dump a
list of threads and their stacks to stderr. Note that it's the real
stderr, not System.err. This is a JVM feature. It can be done anytime
and is a *really* useful debugging feature.

What are the non-obvious causes of OutOfMemoryError: cannot create new

This is happening quite a bit on my Tomcat cluster (linux + sun

thread count (by either ps or the thread dump) is relatively low, often

Can anyone recommend a profiler to use with webapps under Tomcat? Is
everyone happy with OptimizeIt? What about JProfiler? JProbe?
I want to tune a single webapp running under JBoss/Tomcat (no EJBs).

Hi! I'm bewildered by the array of connector options. I'm trying to
hook up a cluster of Tomcat 4.0.4 instances (running in JBoss) behind
Apache 1.3, all running on Linux. I'm looking for a stable,
production-quality option.
It would be really really helpful to me and probably everyone else
accordingly.

I have a conceptual question about load balancing Tomcat4.0.4 instances.
I'm building a *very* high traffic site. Traditionally this company handles
high loads with layering like this:
Non-sticky load balancer
Several NES instances
Many WebLogic instances
This works because WebLogic session
