yes, if maxThreads>minSpareThreads, then threads will be killed off and
the pool will shrink.
and when traffic comes back, it creates new threads, with new names

Then is it normal that an executor stops and removes a thread from the pool?

I

how
can it be removed?
Executors use dynamically sized thread pools. A thread can be removed by
stopping the thread and removing it from the pool.

Subject: Re: Dedicated Thread Pool
Chuck, how can I bind the new<Connector> to a different webapp
directory?
You can't, unless you create an additional<Service> and<Engine> -
which
is likely more trouble than it's worth. Just use the alternate port
when
running the monitor app, and use the regular port for the other webapps.
In
this case, obscurity (not telling users about the alternate port) is
probably sufficient.
Again, JMX-based tools may well give you more and better information -
such
as being able to look at thread dumps on the fly.
