Indeed Jamie,<br>
<br>
there are other problems and the pcmdi3 load problem is getting more
present. But AFAICT this affects mostly data nodes publishing at
PCMDI, as they don't have the possibility to go to pcmdi7, like
others do.<br>
<br>
BADC problem is a different one, which is affecting all data nodes
with heavy traffic. I thik in those cases you get a "connection
reset" message instead of the 403, which means the attribute service
connection is timing out, assume the user does have the group
membership.<br>
<br>
So you are right, there are many other causes that could arise, and
my percentages relate to what I see in the help-desk more than what
actually might be happening...<br>
That's the problem when I try to simplify things :-)<br>
<br>
Thanks,<br>

other problems that lead to 403 at this stage (or maybe its
an earlier stage). One is if the attribute service times
out. (At least thats how I understood it - but I have to
admit I'm not completely sure). I think BADC used to see
this fairly frequently (before they limited the number of
concurrent requests from on IP to the data node), and is one
reason getting to MOHC data is sometimes a bit unreliable.
Stephen has more of the details and can correct me if I've
said anything too wrong.</font></span></div>
