The connector is able to modify what is logged using different configuration options.

Informational messages like those below indicate that a client-side session did not properly close connection to the connector using a regular mysql close() call.

                                        bridgeServerToClientForcedCloseTimeout=500 (ms). Will be closed anyway !

Load balancers (especially physical ones) tend to do this when testing the connector, so these messages are expected when behind a load-balancer. Since the same error could come from buggy application code, the default is to log these circumstances.

If you know where the disconnects are coming from, you can safely disable this feature by setting the tpm option --connector-disable-connection-warnings to true:
