调度启动时，清理过期任务信息报异常

[nmyphp]

调度启动时，会试图清理之前已经过期的任务信息：

// 清除已经过期1天的TASK,OWN_SIGN的组合。超过一天没有活动server的视为过期
this.scheduleCenter.clearExpireTaskTypeRunningInfo(baseTaskType, ScheduleUtil.getLocalIP() + "清除过期OWN_SIGN信息",this.taskTypeInfo.getExpireOwnSignInterval());

如果该目录不为空，就会报异常：

不影响调度

不影响调度

但是，报这个异常，就说明清理不掉过期信息，对吧？这样是不是不符合作者的设计目的和思路？
