[google-cloud-sql-discuss] Re: Aborted connection 29 to db: 'unconnected' user: 'root' host: 'cloudsqlproxy~xxx.xxx.xx.xx' (Got an error reading communication packets)

We are having exactly the same issue, from Compute Engine.

George, this does not seem to be a networking/connectivity issue since this is GCP internal. Any other idea why these things occur? They occur like 20+ times a day - not rare at all.

Thanks!

Hello Peter, 

This type of errors is usually caused by networking and connectivity issues, such as badly configured TCP/IP, faulty Ethernets, hubs, switches, cables. For diagnosing purposes it may be worthwhile trying to connect from a different network and check for any differences in eventual error messages. 

If connectivity is not an issue, your can try raising the max_allowed_packet to a  larger number, upwards from the default value of 1M. 

For more detail, have a look at the "B.5.2.11 Communication Errors and Aborted Connections" online document. 

If you have any more information facilitating our reproduction of the issue, you are encouraged to add it to your reply.
