ARP "U" status, incomplete entry

I have narrowed down some problems to a server having
and "incomplete" status. This state can last a couple
minutes.

As the ARP cache times out and a new ARP request for
the host is sent, there appears to be a 40 second
timeout (I am unable to locate a way to change this)
and the arp -a status for the host is "U" incomplete.
After which time, another arp is sent and the process
continues until a response is received.

Theory is that the arp reply is not making it back to
the server, but I cannot duplicate this state by
arping a non-existant host on the same subnet. In
this case, I the status is always "no entry".

My theory is that the entry must have existed in the
arp cache at the same time it is timing out, a new arp
for the host is sent and the entry does not get
deleted, just status changed to incomplete waiting for
a response from the host.

I am now tired from reading numerous google hits
saying the same thing. Does anyone have some
experience with arp and this type of challenge?

Thanks,

Joe
