Anand-
the suggestion of look elsewhere was a red herring
the problem is your Executor takes thread assignments e.g.
<Executor name="tomcatThreadPool" namePrefix="catalina-exec-"
maxThreads="150" minSpareThreads="4"/>
then Connector is assigned the Executor threadpool
<Connector executor="tomcatThreadPool"..>
