    Description

      MaxScale produces warnings for clients when backend connections are abruptly closed (abruptly in the sense that the client doesn't initiate the process). For Java connections they look as follows:

      ...
      		 
      2018-06-11 15:50:14,953 WARN [org.jboss.jca.adapters.jdbc.local.LocalManagedConnectionFactory] (Timer-8) IJ030027: Destroying connection that is not valid, due to the following exception: org.mariadb.jdbc.MariaDbConnection@6529b7ed: java.sql.SQLNonTransientConnectionException: (conn:848) Connection killed by MaxScale
      		 
      ...
      		 
      Caused by: java.sql.SQLException: Connection killed by MaxScale
      		 
      Query is: SELECT 1
      		 
      ...

      These warnings may be considered as exceptions and require restarts.

      So, I'd like to request some option for MaxScale to NOT produce these warnings.
