I'm seeing this too on a very vanilla lustre setup; it's an
essentially x86_64 RHEL5-esqe system (actually Scientific Linux), the
servers are running the Sun built 2.6.18-128.7.1.el5_lustre.
kernel and the troublesome client is running the stock
2.6.18-128.7.1.el5 kernel with
versions of the lustre-client and lustre-client-modules packages.

The client automounts the lustre filesystem, and it seems to fall over
when doing a du scan of the filesysem, so there's a lot of stat-ing
going on, but not much else.
