Subject RE: What does this mean?

this usually happens when a follower closes its connection to the leader. it is usually caused
by the follower shutting down or failing. you may get further insight by looking at the follower
logs. you should really run with timestamps on so that you can correlate the logs of the leader
and follower.

on thing that is strange is the wide divergence between zxid of follower and leader. are you
mixing processes of different clusters?
