    Description

      Hello,

      we have problems with maxscale in front of MariaDB.
      It's configured as multi master with read/write split.

      As you can see in my Log on Line 76 the Connection drop and all Sessions close.
      This results in problems on the attached systems.

      the mariadb server has no corresponding log entry or warning

      2 things we have seen that could maybe be part of the problem:
      1) line 90 - there is no log entry since 15:08:28 - the connection could be open since 14:24 max. (last error)
      2) line 88 - on this session is the second log line of the last query missing (line 56) - on other connection you can see "Route query to..."
