Notes:
Several scenarios have this problem... so does the real world. If you take a server that holds a replica down without taking it out of the replica ring, synchronization traffic will stack up waiting for acknowledgements from the missing server. If you are going to take it down for a few hours or even a few days, that's probably all right in the real world. In the Practicum, if a server has been removed, take it out of the ring. |
