Bernd,
that is problem not related to stack size.
mountd should encode {sb->sb_dev, inode->i_no} in own structure, but for mount
v1 sb_dev too short to store full sb_dev (it is 16bit, but nfs fid v1 has 8 for
it) bit but lustre client can generate that.
in that case nfsd got invalid NFS fid to client and broken to find correct
inode to get attributes and return -ENOENT. in that case ls -l will show "?"
instead of real inode attributes.
