Nagios process not running or it stops spontaneously

Hi there.

I had installed nagios, it was working great, until i upgraded from ubuntu 8.10 to 9.04, I think the up-gradation might be he reason of the nagios not running. I have removed the nagios and reinstalled as guided in the QuickStartGuide. But the problem still remains.

I donot know why it stops by itself. Or it not starts correctly. Please help me with this.

Thanks
