Down/unreachable confusion

[Israel Brewster]

I have a host being monitored in nagios 3.0 that fluctuates between  
being down and unreachable. The periods where it is listed as  
unreachable typically only last a few seconds to a minute (I didn't  
even think it was checking that often, but whatever), while the  
periods of "down" time (the host really is down) are several hours in  
duration. Naturally, every time it fluctuates back to down (only up  
and down alerts are enabled for this host-not unreachable), it sends  
out an alert, which gets a little annoying.

This all would make sense, however, except for one thing: this host's  
parent, and all other parents back up the tree to nagios are listed as  
being solidly up as far back as the records go. So why is it briefly  
switching to an "unreachable" state, and how can I make it stop? Or at  
the very least, how can I make it stop sending alerts every time it  
switches between these two critical states? Thanks.
