    Description

      The net.tcp.service item (probably net.tcp.service.perf too) does not do a timeout under certain circumstances and blocks an instance of zabbix_agentd (CLOSE_WAIT state).

      How reproducible:
      Always.

      Steps to reproduce:
      1. Put "smtpd_recipient_restrictions = fuuuu" into /etc/postfix/main.cf and restart postfix
      2. zabbix_get -s 127.0.0.1 -k "net.tcp.service.[smtp]"
      3. Repeat above step five times and get a dysfunctional zabbix-agent

      Actual results:
      Getting item data hangs.

      Expected results:
      A timeout while getting item net.tcp.service.
