nagios 进程突然增多一个

       最近折腾搭建了centreon+nagios，发现有时候在centreon中新增服务，重启服务nagios后，机器中会增多无缘无故增多了一个nagios进程，其中一个进程启动时间是我上一次在网页选择导出centreon配置和重启nagios的时间，另外一个nagios进程是我刚刚导出配置和重启nagios的时间，开始有点纠结，不知道怎么回事，以为是centreon或者nagios的bug，但想想又觉得不对，而且发现nagios中服务没有按照设定的周期进行新检测了，上次遇到这问题是系统内核消息队列设置问题，于是查看了系统message日志，果然，发现又报如下错误了。

于是重新设置了
kernel.msgmax = 6553600
kernel.msgmnb = 431072000
kernel.msgmni = 100000

问题好像解决了，有待观察。
