Flavio Junqueira commented on ZOOKEEPER-2104:
---------------------------------------------
The errors in this case don't say much, just that the server can't read/write
from the socket. Is there any issue with your disks? Have you checked the disk
traffic around the time this happened? I'm assumed this happened once, but let
me know if this is reproducible.
> Sudden crash of all nodes in the cluster
> ----------------------------------------

> 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
> Attachments: zookeeper-errors.txt, zookeeper-warns.txt
>
>
> 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.
