I am seeing a ton of orphaned error message for both services and hosts. I am running nagios on a quad core 2.2 GHZ machine running 4 GHZ memory. I will paste my configuration file below. I have the machine sending ndo to a local database sitting on a 170 GB Hard drive. nagios is obcessing on both host and services and sending data to a machine with identical configuration. I am doing failover using NSCA. Please advise on this. nagios.cfg log_file=/var/log/nagios/nagios.log cfg_file=/etc/nagios/commands.cfg cfg_file=/etc/nagios/contacts.cfg cfg_file=/etc/nagios/timeperiods.cfg
