You are most probably running ip_conntrack with iptables, am I right?
Check your /var/log/syslog for messages, you'll probably see alot of
'frag of proto 14' messages when you try to transfer files.

This is a known problem, yet *no-one* can tell me how to fix it, and for
all i know no-one with enough clue (i don't have enough clue ;)) is
planning on fixing it either.

IMHO it is a kernelbug (ip_conntrack bug). I managed to fix it once by
removing certain pieces of code in the ip_conntrack module, but that
could well be a very bad solution ;)

The problem is that sfs mounts the nfs filesystem on the localhost with
rsize/wsize >= 8192 bytes, and ip_conntrack can't handle that (anymore).

Unfortunately it doesn't seem to help to have these connections not
tracked by ip_conntrack.

HTH,
Sander.
