Zabbix server 1.8.1 dies when host trapper is enabled!

[HEMA1]

We are trying to run zabbix 1.8.1, with a Dbdump from zabbix 1.4.6 (host/item/trigger). Zabbix 1.8.1
runs smoothly when trapper is disabled. Problem is: When trapper is enabled zabbix server dies (stops).


Sum up:
Zabbix sever runs on: CentOS release 5.4
DB (separate box) runs on PostgreSQL, Server version: 80309
