restart server, stop error: EM_TARS_UNKNOWN_ERR how to troubleshoot this kind of error?

[TARS-Answer]

Check the adminregistry log. Generally, the service does not exist or the time between the service and mysql is not consistent.

[TARS-Answer]

查看adminregistry的日志，一般是服务不存在或者是服务和mysql的时间不一致所导致的问题。
