MaxScale ERROR 2006 (HY000): MySQL server has gone away

Error: MaxScale cannot be run as root.
Failed to write child process message!
解决办法：# maxscale -f /etc/maxscale.cnf -U maxscale 指定启动的用户

在CentOS7中安装maxscale-2.3.7-1.centos.7.x86_64.rpm

出现执行SQL2003报错提示

mysql> create database testdb;
ERROR 2006 (HY000): MySQL server has gone away
No connection. Trying to reconnect...
Connection id: 23
Current database: *** NONE ***

ERROR 2003 (HY000): Authentication with backend failed. Session will be closed.

查询https://jira.mariadb.org/browse/MXS-1462  ，貌似是一个bug

换成maxscale-2.1.13-1.rhel.7.x86_64.rpm后问题解决
