Hi Chris, Daniel

As a data point

I tried to upload 100 1k files and seemed to meet with success. Most
of then too .3 seconds but about 3 took about 10 times that at 3.3 seconds
It was one ftp session again.
I deleted the files and uploaded 1 of them a second time

For what it is worth I am in Auckland (Parnell, I think that makes the
exchange Airedale <sp> Street) and my ATM shows

  2 PVC 0 101 Yes IP over RFC1483 (LLC/SNAP encapsulation)

I noted that my new ip is a new c-class so I suspect that I may have been
swapped over to a different Redback. Daniel?

So the hang would not seem to be related to ATM errors.

One of the differences betwwen this time and the last was that just before
the ftp session hung I was not pressing hte y key to send quite so quickly.

In my case I have a FreeBSD 3.3-STABLE box that I was ftp'ing from
via a 3.1_RELEASE box that does NAT between the internal network and the
m10

Reload a page I was looking at (through the proxy on the gateway)

Umm.. the ftp session is still hanging so ^c and try again

46 and 49 are 0 bytes and 47 and 48 have gone (I guess that just confirms
that there is a problem)
This time giving a pause between sending the files is going OK.
Still no errors on the ATM results.

It let me delete the files Ok too.
