If mysqld gets its hands on a packet that is too large or corrupted, it assumes something is wrong with the client and closes the connection. If you need large views (for example, when dealing with large BLOB columns), you can increase the query limit by setting the exact max_allowed_packet server variable, which defaults to 1MB.

There are usually no transfers. We had trouble installing solutions because MySQL was getting bad boxes on controller 0. When controller 0 seemed to be removed from the cluster, the build succeeded. Recurring /var/log/containers/mysql/mysqld.log error:

For network problems, use a scheduled round-trip (RTT) ping estimate between the computer that literally hosts mysqld and the computer that the application is requesting from. Send a consistently large file (1 GB or more) to the Turbines client and server, monitor the process with tcpdump, and check immediately if the transfer has occurred.

Suggestions to calm my.cnf-ini in the [mysqld] section – no more than a day and beyond – to keep outdated copies of each used configuration for quick replacement if necessary.

Another workaround and overcoming this warning?
