First I apologize for lack of info. The new machine is a E3000
and the jumpstart version was 2.5.1 (11/97).

Some answers pointed to problems with jumpstart as far as
4/97 vs. 8/97 vs. 11/97. I should have pointed out that this
jumpstart server has jumped many other E3000s recently with
no problem. Some also suggested the arch was incorrect. ie.
sun4m instead of sun4u. I even had someone suggest the
switch be forced to auto negotiate. I negelected to mention
that the machine eventually did boot with no changes to
the JS server or the E3000 hardware. The problem is
intermittant. Maybe 5 boots in a row gave me that message
and then on the 6th it would boot. We had a 3000 crash
a month or so ago and that was the message on the console,
so I asked sun-managers for help hoping this was a known
bug with this hardware since now I was getting it on a brand
new machine. The remaining answers advised testing memory,
reseating SIMMS, etc. which is what I am leaning towards
now. The box has been in production for 4 days though and
has had no problems, which makes that message bug me even
more. As soon as it is down again I will run some mem tests.

Thanks for all your help;
