What OS are you using as the NFS client? I think the most likely reason
for these is that the OS still does some kind of caching even though the
cache is disabled. The cache file is handled a bit specially from
locking point of view, which might cause problems unless the NFS client
really does no caching at all.


Multiple RHEL4u3 hosts running 2.6.9-42.0.3.ELsmp connected to a filer with (rw,nosuid,nodev,tcp,nfsvers=3,rsize=8192,wsize=8192,soft,intr,noac,actimeo=0)
mmap_disable = yes
lock_method = fcntl

Thanks
