[google-cloud-sql-discuss] Re: Sudden and ongoing spike in Aborted connections from GAE

We are experiencing exact same issue

At 2018-06-19 at 12:00:00 PDT, the MySQL client in our GAE app started getting dropped connections with the message:

2062, 'Cloud SQL socket open failed with error: Input/output error'

Simultaneously, our Cloud SQL instance reports:

Aborted connection 1560744 to db: 'XXX' user: 'XXX' host: 'cloudsqlproxy~xx.xx.xx.xx' (Got an error reading communication packets)"  

Ever since it began, a connection fails at least once a minute. Prior to this, we would hardly see a connection issue once a month.

There has been no corresponding spike in connections or queries (we usually hover around 8 connections). Our GAE instances have not had a deployment in this time, so nothing has changed with the client or its behavior.

Any ideas on how to diagnose further?
