[monit] can't stop FPs |

I have a group of machines on the same subnet running monit, where several of
the machines are "check host" each other. These machines don't generate FPs
amonng themselves.
I have another machine on a remote site running monit that "check host" the
group of machines, with
check host hostname-ALIVE with address hostname
if failed icmp type echo count 5
with timeout 1 seconds 3 times within 3 cycles
then alert
The average ping time from remote monit to the group is 65 ms.
The remote monit sporadically generates false alerts for only one machine at a
time in the group (not alerts for the entire group), with the FP moving among
the group. When the remote monit sends an alert for machine x, the other
machines in the group also monitoring machine x send no alert.
I'm talking 2 or 3 FPs/day. Not a disaster but does anybody have any
suggestions how to kill these FPs? I could up to "count 50 with 10 times
within 10 cycles", but I'd rather understand why the above doesn't suffice.
thanks
Len
