For me it dies on any kind of traffic, not just rsync. I even saw this
fetching ISOs using FTP. The machine just died (network-wise; I don't
have console on this machine in the data centre, but I do have a machine
of this type here in the office, so I could build a test setup with KVM).

On the machine that runs stable for weeks now

# uptime
09:51:33 up 47 days, 47 min,  1 user,  load average: 0.14, 0.11, 0.09

I've got TOR running, which uses a sustained bandwidth of about three
MBit (which is not that much, it had about ten MBit for quite a while
with an additional FreeNet daemon running).
