【 使用环境 】测试环境
【 OB or 其他组件 】obclient obproxy
【 使用版本 】4.0 beta
【问题描述】
obproxy是使用命令行带参数启动，启动后日志无报错，但obclient登录失败报【received malformed packet】错误，无法登录root@proxysys。使用mysql客户端登录是正常的。
[admin@bogon obproxy-ce]$ mysql -h127.1 -uroot@proxysys -P2883

[admin@bogon obproxy-ce]$ obclient -h127.1 -uroot@proxysys -P2883
ERROR 2027 (HY000): received malformed packet
【复现路径】
操作系统centos7.9
obproxy启动参数如下：
/home/admin/obproxy-ce/bin/obproxy -p2883 -r’192.168.170.89:2881;192.168.170.89:3881;192.168.170.89:4881’ -c demo01 -e -o 'syslog_level=INFO,proxy_mem_limited=1G’
【问题现象及影响】
影响：obclient无法登录root@proxysys。
日志：
obclient登陆时，日志中对应请求的status是success：
