Problem resolved notification takes 30 minutes

Hi,
can anybody tell why after the problem is resolved zabbix detects it after 30 minutes?

Check intervals, Trigger expressions... These can easily influence the resolution times...

item update interval is 5 seconds, triger expression is in the screenshot

If you ping your hosts in every 5 sec and you have many of those, your server is really busy accepting all that data.. Could also lead to late resolutions...
In my mind anything below 1m is overkill.. and even 1m usually is too often..
