Retry Check Interval is 1m. But after 18m, it took second check, why?
Is there anyone here got this problem?

The "alert summary" report will only show the history of alerts and state changes. So this particular service took 18 minutes to move from a soft critical to a soft OK. Was the service check flapping?

I checked the log. It is as same as the graph.
But I found some "nagios" process' starttime is before I restart them. Is this possible that some process used the old configuration and the other used the new configuration?

Can you post the output that abrist suggested so that we can see all of the most recent logged information?

What notification options have you set on the host? Could you post the contents the respective host's cfg? Are you receiving email notifications for other hosts/services?

Yes. When the host is *real* DOWN, I can receive notifications.
I define a service template for this check, and lots of services use the template. Most time it works well, but sometimes it looks unnormal.
