Subject Re: Issue with New Production Cluster
Date Fri, 29 Sep 2017 13:53:52 GMT
What version?
If you retry immediately, does it reconnect?
Anything in the logs?

What you describe is atypical - timeouts on queries can (and will) happen
occasionally under load, but timeout on connect is atypical. Any sign of
networking issues/slowness/dns problems/etc?
