Hi there Andrew.

I have 2.6.0-test2-mm1 running on two (XP2600 & PII300 named 10.6) machines in this
scenario, and a pIII500 named fs running 2.4.20-rmap15e-fs196-1.4, and a
PIII550 named 10.4 running 2.4.21-rc1-rmap15g.

I have the xp2600 copying large directory trees from each of the three
systems over the network.

I get nfs errors from the activity with the 2.4 systems, but not from the
slowest system that's also running 2.6.

I also got an error "NFS: giant filename in readdir (len                 
792b9a88)!" but it doesn't attribute it to a certain client...

I see this all the time on my 2.4 nfs clients too, so it's not 2.6 specific.
Though it was interesting that there weren't any errors reported from the
2.6 nfs server.

Anyway, I'd like to know what the trouble is with this that I've been having
for a while now.

Thanks
