出现情况：有时候能够获取数据，有时候抱着个错误，
解决：调整server中的Timeout取值，从3s-->10s

16315:20140109:140225.429 cannot send list of active checks to [10.192.0.5]: host [10.192.0.5] not found 16317:20140109:140425.532 cannot send list of active checks to [10.192.0.5]: host [10.192.0.5] not found
这个问题出现在直接删除主机10.192.0.5后，serverlog出现的
将10.192.0.5上的agent停止即可。
========================================================
第一个问题解决方法不是这样的。因为设置后仍然出现了错误，但是如果我将查询间隔从1800s调整到60秒，查看了大概几十分钟，没有出现这个问题。但背后的原因仍不清楚。
