zabbix server deamon hogs cpu! issue

[JamesPatton]

000383:20060721:142801 Getting value of [ifDescr50] from host [ws2003.lan.xxxxx.xx] failed
000383:20060721:142801 The value is not stored in database.
000383:20060721:142801 Error doing snmp_open()


this message repeats itself constantly with various other values(for the same host running windows and an snmp daemon. the serverd and mysql daemon top out at 40-45% cpu utilisation. removing the host through configuration resolves the cpu hogging and extensive error message logging. but what causes serverd to make such a mess of things?

Error doing snmp_open().
I guess your host is not answering properly. Can you get values with snmpget/walk?
And it would be good to always add info about you setup. Version, proxies/no proxies etc...

Thanks, sire. It helped me. Hadn't tried it before...

When that happens, Zabbix should put that item in "not supported" status to lower the load of failed items. SNMP can be slow to respond, what is your "timeout" setting? Zabbix should wait for "Refresh Unsupported Items" time before trying again. (It may try snmp items twice before they go unsupported). If these items are never going unsupported, you may need to increase your timeout setting.
