我得到以下内容:

Native table 'performance_schema'.'file_instances' has the wrong structure
Native table 'performance_schema'.'cond_instances' has the wrong structure
Native table 'performance_schema'.'rwlock_instances' has the wrong structure
Native table 'performance_schema'.'mutex_instances' has the wrong structure
...

并且当它重新启动MySql时出现这些错误.它似乎导致MySql管理员变得不稳定,我得到了很多:

"MySQL server has gone away"
