listener failed: bind() for [[-]:10050] failed: [98] Address already in use

Hey guys,


i know the error says the port, 10050 is in use. But the port is used by zabbix_agentd itself. So why is the zabbix_agentd failing to start.


The agent log:

The netstat confirms it:

To fix this, i have to "kill -9 $PID's that were returned by the (ps aux | grep -i zabbix_agentd) & start the "zabbix_agentd" server on the server.

I found the problem and the solution...
Using the command systemctl list-dependencies i found that i had zabbix_agent and zabbix_agentd, so that was making a conflict, so i removed the zabbix_agent doing systemctl disable zabbix_agent, after reboot everything was fine
