Flavio Junqueira commented on ZOOKEEPER-87:
-------------------------------------------
It looks good to me, but I have one remaining question if you don't mind. Why
are you synchronizing the methods in SyncLimitCheck? There is one instance per
LearnerHandler so I'm not sure it is necessary.
> Follower does not shut itself down if its too far behind the leader.

> Currently, the follower if lagging behind keeps sending pings to the leader
> it will stay alive and will keep getting further and further behind the
> leader. The follower should shut itself down if it is not able to keep up to
> the leader within some limit so that gurantee of updates can be made to the
> clients connected to different servers.
