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
I don't know what patches RedHat has added to it, but I somehow doubt it has all the needed ones. I think 2.6.17 kernel is the first one which doesn't need any patches to work fully correctly.
But anyway those cache things shouldn't really matter, other than annoy you with their existence in the logs :)
