The install went without incident and after some work on the configuration files, I get no errors or warnings when I run "nagios3 -v /etc/nagios3/nagios.cfg". I start nagios using "/etc/init.d/nagios3 start" I open Firefox 3.6.6 and point it at <a class="moz-txt-link-freetext" href="http://localhost/nagios3/">http://localhost/nagios3/</a>, I get a login dialog box, and login with my admin credentials with NO difficulty. Problem is I am getting an error when I click on Hosts, Map, Services, etc., in the left hand column... see below: Also when I run "ps -ef | grep nagios", nagios is not running. The /var/log/nagios3/nagios.log has the following entries (truncated to the last few errors): [1279315908] Nagios 3.2.0 starting... (PID=21610) [1279315908] Local time is Fri Jul 16 14:31:48 PDT 2010 [1279315908] LOG VERSION: 2.0 [1279315908] Finished daemonizing... (New PID=21611) [1279315908] Caught SIGSEGV, shutting down...

(New PID=21763) [1279316062] Caught SIGSEGV, shutting down... Begin Error Message: <h1>Whoops!</h1> Error: Could not read host and service status information! The most common cause of this error message (especially for new users), is the fact that Nagios is not actually running. If Nagios is indeed not running, this is a normal error message. It simply indicates that the CGIs could not obtain the current status of hosts and services that are being monitored. If you've just installed things, make sure you read the documentation on starting Nagios. Some other things you should check in order to resolve this error include: <ol> <li>Check the Nagios log file for messages relating to startup or status data errors. </li> <li>Always verify configuration options using the -v command-line option before starting or restarting Nagios! </li> </ol> 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 <a href="http://www.nagios.org">http://www.nagios.org</a>. End Error Message: Anyone seen this before? I'm really stuck and I have read most of the 358 page manual. Thanks in advance, Art Elsea, Jr. </body> </html>
