 Upgrade kernel and nfsutils on the server.

 Funny, I cannot find the --re-export from any manpages.

 Have you considered SFS ? It can handle re-exports from
 nfsmounts just fine. For more information, see www.fs.net.
 Packages were just installed to non-us/unstable.

 What nfs server are you running on the app-server? nfs-kernel-server
 or nfs-server ? If you had nfs-server package installed you were
 running userspace nfs server even if you had the support in
 kernel.

 2.2.19 and nfs-kernel-server with recent nfsutils are known
 good combination. Anything before has bugs more than enough.
