Something shut down Tomcat, and what you see is the normal result of that.  If the shutdown was unexpected, then either someone sent the shutdown password over the shutdown port - or you've got a rogue webapp that's calling System.exit().  The latter can be prevented by employing a security manager, such as what's described here:

Hi Pid,

Thanks for throwing light on the issue and it is much appreciated, little
keen to know what this error means cause my develoipers debating for a while
now it is
not the application problem.

Could I know what is the Action page is trying to do and gets this
exception, is this possible as this page is my application's Home page and
crashes whole application itself ?

Many thanks.

No, it almost certainly *is* an application problem.  The application appears to be reacting to the failure to establish a connection by doing a System.exit() - which is a capital offense in some places.

Everything in the stack trace is related to the application, not to Tomcat, so you're going to have to take it up with the developers of the app.
