have Tomcat installed on my system. It was working fine till some time back. But after I restarted by system it is not working. This is all that I can see in the logs

It just hangs at this point.

Any clues as to what could be the problem.

Thank you

It looks like you've got a copy of servlet-api.jar inside one of your web applications.
You shouldn't do that.
Tomcat has it's own copy of this jar file that is shared with all the web applications running under it.

Thank you.

Actually this message is not a problem. It was coming even when Tomcat was starting correctly. Now the problem is that tomcat hangs at this point. It does not move forward.

I removed the jar file from WEB-INF/lib. Now this is what comes in the logs. Server is getting hanged at this point

Both your log and your stack trace seem to indicate that Tomcat has started and is waiting for client requests.

Try sending a request to http://localhost:8080 and see if the Tomcat home page displays.

The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.

You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.

Consider Paul's rocket mass heater.
