I'm facing a weird behavior.
I have one Zabbix Server and four Zabbix Proxies, running in differents infraestructures. Sometimes, a randomly host stops sync Zabbix Agent or SNMP data to Zabbix Server, without stoping the ICMP data. And sometimes too, after a few days or hours, the hosts returns to sync.If I delete the host and create it again, the new data starts do sync normally. My Zabbix DB it's in another vm.
Looking in the zabbix_server.log and zabbix_proxy.log I didn't found any errors that explain this. This occurs with different hosts and proxies.
I attached my log in debuglevel=4 zabbix_server.log.
