Hi,

Try changing ServerActive to Server and see what happens.

ServerActive is the configuration option if you want an active agent, Server when you want a passive agent.

Hello, active mode is required, passive mode is normal,。and other machines do not have this issue with active mode

Sorry for the mistake. zabbix-agent2 was in active mode

Hi,

It seems that a process is already listening on that port. I would check which process it is — maybe it's another instance of the Zabbix agent.

Check with: sudo lsof -i :10051

This machine is a client using active mode of Zabbix-agent2 and does not occupy port 10051。Port not occupied, prompt occupied, quite strange issue。
