Dear Jason,

Thank you for link. As per below link. I have started our Window Server 
and problem has been resolved. We are able to start our tomcat. 
But my worry is, I am unable to find out Root Cause of problem. And how to 
handle it in future. 
Do we have any way to monitor buffer space or queue size or do we have any 
other way to free buffer space or queue size without starting the window 
server. 
-------
have you try google?
