    Description

      Hi,

      I'm using MaxScale proxy on more than 40 boxes and now I got a weird error on one of the box.

      After I restarted MaxScale everything is fine again, but I don't know what caused the problem.
      I don't use the read-write splitting I only use the "read connection router" ability.

      If you need anything else just let me know.
