      Description

      Folks,

      I've seen this happening again on 2.2.16. We worked together some time ago and sorted that out but, using the ReadWriteSplut Router; not sure if the ReadConnRouter, being used this way, also has some similar code to create this situation. This below error was happening when running 2.2.16:

      Packet received out-of-order. Expected 1; got 3
      

      So, we downgraded Maxscale to 2.2.4, and then, the error stopped occurring. Interesting is that we didn't change anything in the configuration file, just replace the .deb package. Below, the configurations in use:
