This is a new installation of nagios 2.10 (really groundwork, which I'm starting to think is a total POS).
I am getting flooded with "Host UP" alerts. I get an occasional down alert, but most of the UP alerts have no associated DOWN alerts.
The state duration in nagios shows that the host hasn't changed from UP in days, however I just got a page a few minutes ago that it was UP.
I tired a newer version of check_icmp, but that didn't help.
The OS is RHEL5.2, all updates.
Might be related, might not, but I'm not getting any alerts for services, even ones that are red right now.
All services and host are set to email 24/7, on up, down, and recovery.
