why is nagios pinging servers?

[Chris Stankaitis]

The issue I believe is your check_command... what happens is when your 
freshness expires it will FORCE an active check and use the 
check_command you have defined... thus as you have defined check_ping it 
will ping, so you want to define a dummy command that will pass an 
"UNKNOWN" or "CRITIAL" sate when you service becomes stale.  it's pretty 
well outlined in the docs for the freshness checking, take a look at 
them again, they even give you the "dummy" script code.
