Offhand seems like a server bug. Might conceivably happen if there was some confusion whether the client was authorized to access that export? --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
