When snmp agent falls agent zabbix come in critical degradation!

[testos]

Greetings.


I have several snmpv1 items type in certain machine. If agent SNMP falls, the agent zabbix great slows down, as much that it do not update other items. When setting DebugLevel=4 in zabbix_agentd.conf, many “Sleeping for x seconds” messages are showed in zabbix_agentd.log.
If agent SNMP falls, all monitoring activity is stopped in this host!
Trying several agent Timeout vainly.

Regards.

Details zabbix queue continuously grows with items of this host.

Top of queue appears SNMP items with next chek "01.01.1970 00:00:00"
and below reminder same host items
Nobody snmp monitoring working has reproduced this problem?
It would be enough stoping snmpd service and watching zabbix queue…

Thanks.
