hi ,
 i am getting the following error in nagios

Whoops!

Error: Could not read object configuration data!

Here are some things you should check in order to resolve this error:

   1. Verify configuration options using the -v command-line option to
check for errors.
   2. Check the Nagios log file for messages relating to startup or
status data errors.

Make sure you read the documentation on installing, configuring and
running Nagios thoroughly before continuing. If all else fails, try
sending a message to one of the mailing lists. More information can be
found at http://www.nagios.org.

i have checked everything and verified the configuration options.
its works properly in the begining,once i stopped nagios and restarted
again it creates this problem and am getting the above error.
