I have experienced this issue with a couple of other machines in the
colo, although I cannot remember exactly which ones (proxy[1-4] iirc).
I think Stacy replaced our switch, have we experienced these issues on
the new switch? Also I know that bastion (and others) had iptables
rules that caused burst limits to get dropped. For example if you
logged in and did a "cat /var/log/messages" eventually the connection
would hang.
