Experiencing constant bugus notifications (beta4)

[bbrendon]

I have many hosts with this trigger set.

{hostname:system[procload].nodata(620)}

The hosts are reporting procload every 300 seconds. The latest data tab in monitoring shows that the information is current.

Unfortunately, i'm getting constant notifications that the servers are down from this trigger. The events tab shows ON/OFF for many triggers at a good rate.

Luckily I have all notifications to the same group and I have currently removed everyone from the group. I'm investigating futher, but I don't see anything wrong with my configuration yet.

Notifications appear every 5 mins.

According to the docs, nodata() is for trapper only. What is a trapper? It was working great with active checks until the upgrade.

In addition, i tried using sum and count with various items but haven't been able to replicate nodata with them.
