[hobbit] Strange pinging issue

[Josh Luthman]

Unfortunately my issue is still nagging at me!

I've found that hosts on the same switch and hosts on one LAN have the
issue, while some hosts going through a router are good, others are bad.

Everyone of the red pages say it is "System unreachable for 1 poll periods
(0 seconds)" and never lasts more then a minute.  Anyone have a clue where
to look?
