I'll presume you've grep'd for 'kernel' and 'nfs' in /var/log/messages
and the output doesn't suggest a problems with either.

And that RPCNFSDCOUNT in

    /etc/sysconfig/nfs

has been changed from it's default value of 8 - if not I would double
it and restart nfs.

Then I'd try the following if you haven't already

      /usr/sbin/exportfs -rv
      /etc/init.d/nfs restart

If nothing changes, then look at the file rmtab, etab, xtab (later may
be empty) in

     /var/lib/nfs

and if the rpc.statd daemon is running, in

     /var/lib/nfs/statd/sm

and see if you spot anything screwy when you access the mounts.

And if nothing works, I'd try renaming the filesystem from '10' to
'ten' - you could be tripping on a bug..
