<div></div>I really don't think my problem is packet loss or anything like

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
