Looks like maybe your network is faulty. The crc error means the OSD received a message with a checksum that didn't match. The dropped message indicates that the connection (in this case to a client) has failed (probably because of the bad crc?) and so it's dropping the outgoing message. This is intentional; if the connection is re-established from the other end that state gets replayed and handled properly. -Greg
