galaxysql process crashed during sysbench tests about polardbx-sql HOT 2 OPEN

这个看起来像请求中间的no_error的Expectation违反了（这个是请求流水线的一个机制），查看下对应的库
/home/admin/drds-server/logs/库名/tddl.log
有没有其他同时间的报错信息

from polardbx-sql.

1、又测试了一次，/home/admin/drds-server/logs/tddl/XLog.log如下：

2、对应数据库sbtestdb下的日志/home/admin/drds-server/logs/sbtestdb/tddl.log
