Parada no monitoramento dos Hosts

[jhonthan]

Boa Noite.
Tenho percebido, que de uns 15 dias para cá, meu Zabbix Server, tem parado de monitorar os hosts com frequência, como se o daemon do serviço parasse de rodar, conforme print:



No entanto, ao remover o serviço do zabbix-server, e iniciá-lo de novo, em :
/etc/init.d/zabbix-server

o mesmo volta a monitorar, e atualizar os hosts.

Peguei uma simples referência no log:

Alguém ja passou por um problema desses ??

Bom dia,

Já verificou se não é um gargalo de rede?

Abraço!

Bom Dia elvis.pompeu.
No caso não creio que seja um gargalo de rede, pois o Zabbix é um server dedicado, possuindo somente 3 hosts por enquanto.
Achei que pudesse ser algo relacionado ao host Windows 7, pois é o que apresenta o ultimo erro, antes de parar de monitorar.
Mas mesmo desabilitando o host, o problema continua.
