      Maxscale 2.2.4 with rwsplit

      Description

      Testing full sst-sync and wanted the master-node to be able to available in maxscale,
      So I added the following config to maxscale:

      master_accept_reads=true under service
      available_when_donor=true under monitor
      

      When restarting, maxscale will die with the following error:
