Hi Michi,
1) The follower stops following the leader when it gets an exception on the
socket (Follower.followLeader):
...
while (self.isRunning()) {
readPacket(qp);
processPacket(qp);
}
} catch (Exception e) {
...
I believe we are setting the timeout like this: self.tickTime *
self.initLimit. Check connectToLeader().
2) I believe we fixed this bug in 3.4.6 and the change is pending for trunk.
Check ZK-1808 for 3.4.6 and ZK-1810 for trunk.
