    Description

      Hello,

      We recently upgraded from maxscale 6.4 to 23.08.
      Since then, we notice in the maxscale logfile error like these :

      2024-01-23 11:29:07 error : (2039) (IM46130D-Service); Lost connection to backend server: Network error: 104, Connection reset by peer (IM46130D1, session=2039, conn_id=4531072)
      2024-01-23 11:29:26 error : (2062) (IM46130D-Service); Lost connection to backend server: Network error: 104, Connection reset by peer (IM46130D1, session=2062, conn_id=4531091)
      2024-01-23 11:29:38 error : (2071) (IM46130D-Service); Lost connection to backend server: Network error: 104, Connection reset by peer (IM46130D1, session=2071, conn_id=4531101)

      It seems whenever a connection reaches interactive_timeout it is then reported as an error in the log file (I can see it clearly by doing some "list sessions", when 600s reached --> reported as error). I've tried to set connection_keepalive=30s to the service in maxscale config file but it does not help.

      On the backend mariadb :
      interactive_timeout=600
      wait_timeout=600

      Service in maxscale :
      [IM46130D-Service]
      type=service
      router=readconnroute
      router_options=master
      servers=IM46130D1,IM46130D2
      user=xxx
      password=xxx
      connection_keepalive=30s

      I've found a similar issue saying it is fixed but I'm still having the problem. Here :
      https://jira.mariadb.org/browse/MXS-4440

      Could you have a look?

      Thank you
