What is that? I’ve updated nagios from 2.x to 3.0.3.

Are you sure you have configured apache.conf and cgi.cfg in your /etc/nagios/ folder properly?

Sure, it’s strange problem, sometimes it happened once in a hour, some times once in a day, sometimes this error stay 2-3 hours. I cant resolve thing that cause this error.
