My zabbix environment has a zabbix server, zabbix db, zabbix proxy, all agents connect to proxy.
zabbix version is 3.4.8, operation system is redhat 7.4.
Lately，there are lots of alerts " xxx is unreachable for 5 minutes", and the those alerts will recovery in 15 - 20 mintues. and this happens once a day, but not at the same time.
this proxy connect about 400 agent, about 150 thousands items.
And I found, when the alerts happen, there is a proxy alert "Zabbix busy data sender processes is 100%" is happen.
Any one can help me resolve this problem?
