Sorry, coming in a bit late and a bit fuzzy. I feel like we didn't ask you to properly clarify the problem.
So reports in core are done by reading through the flat files. If you have a big environment this can take a devastatingly long time. It is what it is, can't really be fixed easily. Often times apache will timeout the CGI prior to the results finishing processing. This is easily fixed by adjusting the apache timeout directive:
http://httpd.apache.org/docs/current/mo ... ml#timeout
This can be verified by looking in the httpd error_log which is the original direction this thread headed, but it seemed to veer way out in left field.
Does it seem like that could be the problem?
A good reference thread:

Then I do not believe you are looking at a timeout issue caused by Nagios needing lots of time to create the report. Something else is going on.

timeout in apache2.conf
Code: Select all
#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300
its already 5 min. do i have to increase more than that?

No. Something else is going on that is causing Apache to time out. If you want to try it, just to prove it, set that to 600, which is ten minutes. I'm willing to bet it will still timeout.
It is possible for you to recompile your Nagios binaries and reinstall them? I wonder if they did not get created correctly in the first place. Were they made on this machine or made somewhere else and moved to this machine?

I installed new version of nagios on new server but copied old nagios config files and scripts and made changes to the conf files accordingly.
changed timeout to 600 still same error.

I have a hunch you have an Apache problem, not a Nagios problem at this point. I'd really look closely at the /var/log/httpd/error_log for more information.
