Hi,

I updated my zabbix from 3.0 to 3.2.1 because some features of 3.2.1 was interesting to me.
I use zabbix to monitor =~ 400-450 hosts like Fortigate, Mikrotic, Windows & Linux servers.
Before the update everything was OK but since last Thursday sometimes i have many hosts loosing their connections to Zabbix server and trigger the alert. They come back like 5 or 10 mins after the alert. It's look like just before the problem there is a huge item queue. But that's all i noticed

It's very very annoying for the support team because a hundred or alert pop on the screens for nothing because host and Internet links are OK

I attached a screen of some graphs of the last 4 days. If you need anything more just tell me i will send it to you

Thanks for help !
