David Lao commented on ZOOKEEPER-2104:
--------------------------------------
In my case the logs and snapshots are on separate drives. I noticed the net
traffics, with the resource monitor app which is part of the Windows OS, were
from the leader to followers on port 2888. I was seeing ~15 MB/s traffic
between the nodes. Will try to increasing the snapshot count (though I'd think
the default 100k transactions is plenty for the particular running workload).
There are two distinct ERRORs from the log (see attached), one appears to be
due to broken connection and the other is
java.nio.channels.CancelledKeyException (reported in ZOOKEEPER-1237). The
broken connection error happens only once when server start.

> Key: ZOOKEEPER-2104
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2104
> Project: ZooKeeper
> Issue Type: Bug
> Components: server
> Affects Versions: 3.4.6
> Reporter: Benjamin Jaton
>
> In a 3 nodes ensemble, suddenly all the nodes seem to fail, displaying
> "ZooKeeper is not running" messages.
> Not retry seems to be happening after that.
> This a request to understand what happened and probably to improve the logs
> when it does.
> See logs below:
