Zabbix agent on host is unreachable for 5 minutes

[Husabuse]

Hi!

I'm a happy user of Zabbix for some time now...and so far, there is only one real issue, but an irritating one.

All monitored hosts are running fine, apart from every now and then, one out of 200+ where zabbix throws "Zabbix agent on host is unreachable for 5 minutes", and it comes back ok, then throws the alert, and this continues until the server has been restarted.

Restarting the zabbix agent service doesn't help.

Anyone?

Tried zabbix-get -s hostname -k agent.ping - and when the host is responsive according to zabbix I get a "1" back as a result.

When it's "unreachable" I get [24375]: Timeout while executing operation.

Reboot the monitored windows host - problem solved - and for obvious reasons this is not a valid solution really...

Noone...?
