If there's only one machine running the Apache server, and the svnserve
is on a different one, then another hint may be that the apache machine
locked the files locally but not on the NFS server, so it worked fine in
the one-machine case. AFAIR some NFS clients had that behavior that
locks were respected locally, even if they were not propagated to the
server.
