[google-cloud-sql-discuss] Re: Increased rate of "MySQL server has gone away" errors

Hello, 

Have you gone through the Issue link[1] referenced by George in one of Messages? I recommend that you do that as this issue may be related. 

That being said, I believe there are a number of reasons that may be responsible for this type of errors. For example, I gathered that this error message may be reported following errors about attempts at reading communication packets. 

Of course, when you have errors about communication packets, it often suggests that an existing connection is perhaps terminated improperly. Aborted connections happen because of unclean's connection closure, or a networking issue between the Cloud SQL MySQL instance and the client.

Whether or not this is the situation on your Case would require reviewing your Project/setup and the logs to understand what led to the errors, which is why I recommend that you contact the GCP Support Engineers[2] so that the team could help with determining the cause of the error particularly on your CloudSQL Instance.
