> Please let me know what other information I should contribute. My guess is
> that this is just a timing problem; because the zookeeper instances were up
> and running (on the same server).
> Also I noticed that there was no election-rote created after this error - so
> my guess is that routes in this state would never run, effectivly leading to
> a dead-node (failover to this node would never happen).
