Just checking, you're not storing the repository on an NFS-server, are
you? Use the local file system.

From the FAQ:

---
Should I store my repository on a NFS server?
No, don't ever do that. Berkeley DB does not support storage of
databases on remote file systems. Some NFS servers claim that they
explicitly support use of BDB on NFS-mounted partitions, but we've
only ever seen BDB databases get corrupted when living on an NFS or
SMB network drive.
A working copy, however, can be stored on a NFS server (i.e. your home
directory is on a NFS server). On Linux NFS servers, due to the volume
of renames used internally in Subversion when checking out files, some
users have reported that 'subtree checking' should be disabled (it's
enabled by default). Please see NFS Howto Server Guide and exports(5)
for more information on how to disable subtree checking.
