File version problem with 2.6.23.11

[Harry Edmon]

I am running the stock 2.6.23.11 kernel.  I am running an "rsync" 
process on my server to duplicate files from another server.  One of my 
clients is not seeing the updated version:

server:

-rw-rw-r-- 1 marka ldm 2577 Dec 17 10:22 data/ecology/2007121718.dec

client:

-rw-rw-r-- 1 marka ldm 378 Dec 17 10:11 data/ecology/2007121718.dec

The "ls" output was done 7 minutes after the update.  Here is the mount 
options for the client:

imist2:/data on /home/disk/data type nfs4 
(rw,noatime,intr,proto=tcp,rsize=32768,wsize=32768,addr=192.168.1.12)

Here is the export options on the server:

ifa2(nohide,rw,no_subtree_check,async,no_root_squash)

If I do an ls -l on the whole "data/ecology" directory on the client it 
"gets better" and sees the correct file size.

Any ideas?  This seems to be a kernel problem I have seen before, and 
has been fixed before.
