Yea the link above is the kill -QUIT output.

We do have aanother  webapp connected to an ActiveMQ broker so that makes
sense.  I assumed the same as you Charles, that Tomcat was "waiting" for
work, but we were running a load test at the time and the responses were
coming back slowly.  Trying to nail down why Tomcat was waiting for requests
, yet wouldnt respond to any when directly connected to it.  I

And yes these were all http requests for the web applicatoin for our load
test.
