This may be due to an NFS problem.

Here's a case where readdir would return the same name,
yet a new pointer, each time, forever:

     NFS readdir never returns NULL when processing directories with very many\
       entries (i.e.,>300K)

This does not look like a NFS problem but like a Linux problem....

If it was an NFS problem, it would happen regardless of the implementation of
NFS server and NFS client.

I guess the underlying file system is ext3/ext4. If so, ext3/ext4 and NFS need to be patched. The reason then is a compatibility issue with NFSv2 and 32-bit user space (32 bit long values from telldir() ). We also already run into it with FhGFS.
