<DIV></DIV>I really don't think my problem is packet loss or anything like
that - I have a hard time believing that <A
href="http://127.0.0.1">127.0.0.1</A> or the public IP is unreachable of
itself. It should noted that the duration is never more then a minute,
sometimes 7 seconds up to 45 seconds - definitely not getting two polls in
(according to what I've read it polls every 60 or 120 seconds, never quite
that 7-45 second duration). <BR><BR>If I ping the host from a shell I never
get any packet loss or any issues, yet Hobbit still thinks it was down for a
few seconds. This is <SPAN style="FONT-WEIGHT: bold">every</SPAN> host I
have monitored, by the way. <BR><BR>Josh<BR><BR>
