Each nagios instance starts up without errors, and runs fine when it's the only instance running. However, when more than one is running, the log files indicate that each instance is receiving some check results from hosts/services on another instance... I see messages like this in /local/nagios2/var/nagios.log, when the host "hadar" is configured in the /local/nagios1/etc/hosts.cfg config file:

sound like your different instances are sharing the "check_result_path" 
(nagios.cfg).

Hopefully you didn't upgrade from nagios 2 without applying the changes 
against a nagios 3 main config? ;)
