If there is slow response from db I see this stack trace and the open files
goes high and the only way to open files go down is to remove the instance

After the browser disconnects and data is written to the response

That's good. Many of the reports I've seen on this list have been people
moving up to Tomcat 6 and experiencing /more/ memory problems --
indicating that TC6 uses a bit more memory. I'm glad you are having the
opposite experience.
I haven't used 5.x but 6.0.14 does seem (I'm still testing)
that another server has sent to it. Which rarely takes more
than a few seconds each and no more than 2 at a time.
Cheers
James
