I am having a problem getting odd ESTALE (Stale NFS file handle) 
errors.   The server and client are both amd64 architecture.   I am 
runnning a simple csh script on the client with the following:

if (! -e /home/disk/data/gempak/upperair/latest ) then
    mkdir /home/disk/data/gempak/upperair/latest
endif

The script randomly comes back with:

  mkdir: cannot create directory `/home/disk/data/gempak/model/latest': 
File exists

When I do an strace I am seeing the following when it fails:

20745 stat("/home/disk/data/gempak/model/latest", 0x7fff56ed9580) = -1 ESTALE (Stale NFS file handle)

...

20751 mkdir("/home/disk/data/gempak/model/latest", 0777) = -1 EEXIST (File exists)

The kernel version of the client does not matter (I have tried 2.6.34.5 and 2.6.35.3).   But the server kernel does matter.   It occurs with 2.6.35 and 2.6.35.3.   It does not with 2.6.34.5. 

The ESTALE only occurs with "stat" and "lstat" in the scripts I have tried.  Attached is my configuration file from the server.  The mount on the client is:

imist2:/home/data on /home/disk/data type nfs (rw,noatime,intr,proto=tcp,addr=192.168.1.12)


 Any ideas?
