    Hello.
    I encountered this problem in version 3.0.1.
    How was the problem solved?

      Hi,

      Still isn't in my case... The problem goes "away" simply by logging in to the Web Console. Which makes it hard to debug.

      I've mitigated the issue by using Proxies that are managed "passively" from the Zabbix Server... Odd thing is this happens only on 1 of my 16 Zabbix servers, and they're all clones of one-another.

      I was waiting for my company to buy the Support package from Zabbix, but at the rate they are going, I will have to take a deeper look at it. What makes it hard to debug is that it's not happening regularly: Sometimes once a month, sometimes 2-3 times in the same week. and as soon as you start poking around the web console, the Active pollers "unfreeze" and starts processing again.

      G.

        Version 3.0.1 has it's own problem. Luckily, it's already fixed in 3.0.2rc1.

        Regarding that good old one... Has anyone tried to monitor what happens with incoming TCP connection queue on Zabbix server listen port using "ss -l"?

          I think I'm experiencing the same problem as this on 2.4.8.

          I'm using exclusively active proxies/agents
