ZABBIX 1.4.2をPCにインストールしましたが、Agentから情報を吸
い取ってくれません。ServerとAgentは同じPCで動かしていて、
ポート番号はデフォルトのままです。netstatでみても、Serverと
AgentはうまくBindしているようです。
zabbix_server.confでデバッグレベルを4にしてみたら、下記の
ような不可解なログが定期的にでています。
設定画面→Configuration→HostではStatusはMonitoredですが、
AvailabilityはUnknownです。。
DBの構築時にSQLで初期データを入れたときに幾つかエラーが
出ていたのが気になります。postgresqlをDBにする場合の何か
気をつける点はありますか？

・CentOS5
・ZABBIX 1.4.2
・postgresql-8.1.9-1.el5
・net-snmp-5.3.1-14.0.1.el5
・php-pgsql-5.1.6-15.el5
