When I first startup nagios 2.0, everything is fine. All checks come out okay and everything is good. But, when I reload nagios for a configuration change, or after a couple days of running, my root host (a core switch), reports the error out of bounds 127 error. Since this is my root host, all other hosts are marked as unreachable since this one reports an error. The only way I can fix this after that error is reported is to stop nagios, delete retention.dat and status.sav and restart nagios. Then its fine again until I have to make a config change or it runs for a few days. These are the latest plugins, they have the correct permssions and ownership on them and they are located in the right directiory, with the correct perms and ownership.
Any ideas on why this fails after a period of time or on a config reload?
