    Description

      Steps to reproduce:

      1. Upgraded zabbix agent from 6.0 to 6.20 bate
      2. I used the command "for i in {1..100};do sleep 60;ss -p state close-wait | grep "zabbix" | wc -l >> /tmp/a.txt;echo "    ";date >> /tmp/a.txt;done" to generate a text file.

      Result:

      1、Active checking becomes unknown

      2、The "Cannot create data pipe: [24] Too many open files" error message appears

      3、There are too many tcp connections that are in close-wait.

      4、The number only decreased after I restarted agent service.But if I restart the server service it doesn't work,the agent is still connected to the old server 
      See screenshot...
      Expected:
      The tcp connection is disconnected after the zabbix agent finishes sending the data.
