NFS server problems

[Bernd Walter]

I often see clients getting NFS errors when the server mounts an
new and unrelated filesystem.
This is especially annoying as one of the NFS servers is used to
read removeable media.
I also get errors when a server just reboots - maybe these are related
to boot mounts?
Unfortunately my environment isn't very good to isolate the problem
so my hope is that someone with more NFS knowledge and a test
environment can reproduce the simptoms.
My assumption is that it just happens for write access, but I can't
tell for shure.
Mounts are UDP over IPv4 with statd/lockd running.
