False "host has just been restarted" triggers

[sunmicroman]

I am new to Zabbix and am liking it so far, but one thing I am trying to figure out is one of the default triggers for hosts. I keep getting alerts about some of my hosts running the agent having "just been restarted" when I know the host computer has not been restarted. I am getting a lot of these false alerts, actually. What is the criteria for that particular trigger and what can I do to make it actually accurate?

I believe this acts on the "uptime" of the server. If the uptime is not accurately reported it could result in a false positive.

I believe by the date of the post, this problem has been resolved or abandoned. But it would also be important to also inform the Zabbix version and the trigger expression. In our system, we check if the uptime is less than 10 minutes. I haven't heard that a server provided incorrect uptime.
