I'm seeing a similar thing with a few web-apps which need locking over 
nfs with U2 kernel and nfs-utils. Never got it tied down to anything 
specific for a bugzilla entry so I had to resort to running those boxes 
with pre-U2 kernel and U2 nfs-utils. Gonna try -15.0.2 kernel soon but I'm 
not exactly optimistic about it.
