Flavio Junqueira commented on ZOOKEEPER-87:
-------------------------------------------

Here are a few comments, German:

# Please make the initialization of SyncLimitCheck fields explicit.
# Please add blank lines between method definitions (http://www.oracle.com/technetwork/java/javase/documentation/codeconventions-141388.html#487)
# The test case does not fail for me when I only apply the test case changes. I haven't looked
too closely into it to determine the reason, but I was wondering if it fails for you.

> 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.
