Wrong value in latest data

[burn1024]

I'm having a situation when the value for an item is displayed incorrectly in monitoring > overview > data (thus triggering the alert), but when I check "500 latest values" I see that it's actually correct. See the attachments.

This started when I transferred my Zabbix 1.8.1/Postgresql 8.4 installation to Zabbix 1.8.16/Postgresql 9.2 (another server). After spending a day on this problem I decided to try Zabbix 2.0.5. It persisted. The item is "numeric unsigned", "decimal", "zabbix agent (active)".

The weirdest thing is that the same item works fine at another group of hosts.

Please help. It's driving me crazy.

Any ideas?

Wrong value in latest data

Hi !

I have some equipment with the same result (C1721).
I think there are some network error which causes the false values.

The SNMP uses UDP not TCP.

What's your environment? Did it just started to happen on its own? I don't believe it's a network error. The correct value is submitted to Zabbix, but it doesn't make it to latest data somehow.
