Your clients (if close to CENTOS5.1: upgrade) may be hitting:
https://bugzilla.redhat.com/show_bug.cgi?id=321111
http://bugs.centos.org/view.php?id=2635
Client caching is impaired, hits server VERY much harder, more
often than necessary (slow down on clients, network, and server).
To demo: loop stat of a mounted dir's file that does not exist,
the deeper (dir depth) the better.
