Germán Blanco commented on ZOOKEEPER-87:
----------------------------------------
Thanks again for your comments Flavio,
it did fail, but I hadn't tried it enough. Sometimes it didn't fail.
There was a problem in the test, it didn't reply to pings from the leader.
So if the LearnerHandler decided that there was a ping timeout before it
decided that the proposal had timeout, then the test case passed (it finishes
before it had a chance to notice the other timeout). And the timeout period for
both events is the same.
I will upload the corrected patches with your comments updated in a moment.
> 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.
