Travis Crawford commented on ZOOKEEPER-803:
-------------------------------------------
Maybe 8-10 clients were running the buggy code. Not too many.
> Improve defenses against misbehaving clients
> --------------------------------------------
>
> Key: ZOOKEEPER-803
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-803
> Project: Zookeeper
> Issue Type: Bug
> Affects Versions: 3.3.0
> Reporter: Travis Crawford
> Attachments: connection-bugfix-diff.png
>
>
> This issue is in response to ZOOKEEPER-801. Short version is a small number
> of buggy clients opened thousands of connections and caused Zookeeper to fail.
> The misbehaving client did not correctly handle expired sessions, creating a
> new connection each time. The huge number of connections exacerbated the
> issue.
