So, I assume the clients mount their /home from a (the?) server via NFS?
If so, I used to have a lot of problems with the old nfsd, that used
to die on my every so often (escpecially if two clients mount and read
from the nfs disks at the same time). This was solved by upgrading to
a more recent nfsd. But alas, you don't indicate that any nfsd dies,
so you may be running into another problem. Still, upgrading the
server's nfsd (from the netstd package) may improve matters.
Currently installed on my system (without problems):
$ /usr/sbin/rpc.nfsd -v
Universal NFS Server 2.2beta25
$ dpkg -l netstd
ii netstd 2.13-1 Networking binaries and daemons for Linux
