How to run tomcat on linux

I am facing problem while ruing tomcat server on 'windriver linux' when I start tomcat server as

./startup.sh

And I go to 'serverip:8080' i don't get tomcat webpage everytime, sometime it takes lot of time to show tomcat home page or sometime it doesn't show up at all. I have checked ruing processes on windriver terminal but it shows tomcat is ruing in it. please help me
Thanks in advance
