是一套主备集群，主库实例宕机，主库守护并没有拉起主库实例，主备发生切换。

这是dmwatcher.ini

DW_TYPE                  = GLOBAL  #全局守护类型
DW_MODE                  = AUTO  #MANUAL：故障手切 AUTO：故障自切
DW_ERROR_TIME            = 60  #远程守护进程故障认定时间
INST_ERROR_TIME          = 30  #本地实例故障认定时间
INST_RECOVER_TIME        = 60  #主库守护进程启动恢复的间隔时间
INST_OGUID               = 453331  #守护系统唯一 OGUID 值
INST_INI                 = /dmdata/DAMENG/dm.ini  #dm.ini 文件路径
INST_AUTO_RESTART        = 1  #打开实例的自动启动功能
INST_STARTUP_CMD         = /home/dmdba/dmdbms/bin/DmServiceDM1  #命令行方式启动
RLOG_SEND_THRESHOLD      = 0  #指定主库发送日志到备库的时间阈值，默认关闭
RLOG_APPLY_THRESHOLD     = 0  #指定备库重演日志的时间阈值，默认关闭

问题1：宕机原因是？
问题2：主库宕机了，守护为什么没有自动拉起呢？
