Kennan,
I can agree partially to yours. But if you see him, he doesn't know about
the impact of JVM and tuning parameters, as he mentioned in his email. Do
you expect him to take a lead in fixing that? I have seen the projects
losing its focus by the nature of peoples deviating to get their intere
Yes, But that doesn't mean that we can put and point on developers for any
problem.

Stephen,
In fact, cap it at 10 and watch the app dring to a halt before it even
gets going. This is a pretty compelling example. If the pool is drying
up, they're definately screwing up.
Whoa there pardner: I am not going to deliberately cripple a production box.
The problem has been demonstated

velopers and him. If he is very keen, why
not one of the developers responding his thread and get the issues fixed for
the project.

Being yourself as SYSADMIN for UNIX and Network, it would be nice that

Easy for you to say.
Let's face it: these guys have a connection leak. Plain and simple. Your
devs need to find their leak. It is demonstrable.
Antonio,
And bad. Every time I restart, Tomcat loses the state information for
established login sessions. Customer don't like that.

Your developers may be right in the end but with wrong arguments.
With virtual hosting or several webapps you have just one jvm.
But each webapp has it's own classloader.
If the pool is loaded by the wepapp classloader you will have
one instance of the pool for each webapp.

Stephen,
I am having a problem with tomcat opening up up a number of connections to an
oracle server that never get closed. This causes the number of open
connections to build up over time and, eventually, causes the oracle server
to use all of its swap.
That's not good :(
