Fresh install of Nagios 1.3, on Red Hat EL 4, Update 2. Compiled and installed straight from the documentation. About 450 hosts monitored for 3 services.
Whenever I reload the service to add new hosts/change the configuration, Nagios sees the hosts as down, even though immediately before the reload, the hosts were up. When this happens, there are a flurry of e-mails sent, and then once the machines are re-polled by Nagios, there are more e-mails sent about the recovery.
This behavior doesn't exist on our v1.2 installation.
Anyone have any ideas? Thanks in advance for the help!
