If its a linux binary did you mount the NFS filesystem with -X?
From the end of compat_linux(8):
Linux executables cannot handle directory offset cookies > 32 bits.
Should such an offset occur, you will see the message ``linux_getdents:
dir offset too large for emulated program''. Currently, this can only
happen on NFS mounted filesystems, mounted from servers that return off-
sets with information in the upper 32 bits. These errors should rarely
happen, but can be avoided by mounting this filesystem with offset trans-
lation enabled. See the -X option to mount_nfs(8). The -2 option to
mount_nfs(8) will also have the desired effect, but is less preferable.
