      Hello,

       

      We are having trouble with a centos 5.9 system and zabbix net.tcp.listen at zabbix 3.4.14 agent (from zabbix rpm repo)

       

      # cat /etc/yum.repos.d/zabbix.repo
      [zabbix]
      name=Zabbix Official Repository - $basearch
      baseurl=http://repo.zabbix.com/zabbix/3.4/rhel/5/$basearch/
      enabled=1
      gpgcheck=0
      gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
      
      [zabbix-non-supported]
      name=Zabbix Official Repository non-supported - $basearch
      baseurl=http://repo.zabbix.com/non-supported/rhel/5/$basearch/
      enabled=1
      gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
      gpgcheck=0
      
      # rpm -qa | grep zabbix
      zabbix-sender-3.4.14-1.el5
      zabbix-agent-3.4.14-1.el5
      

       

      # grep "^[[:space:]]*80:\|^[[:space:]]*443:" /proc/net/tcp
        80: 9607BC0A:196D D304BC0A:1F49 01 00000000:00000000 02:00001582 00000000   521        0 164153422 2 ffff81007a412080 208 40 26 3 -1               
       443: 9607BC0A:CF6A D304BC0A:1F49 01 00000000:00000000 02:00005901 00000000   521        0 163982489 2 ffff81003f283980 206 40 30 3 -1               
      

      I'm attaching both strace output as requested on similar issue (ZBX-10431)

      At strace of 443 we can see how zabbix try to open tcp6 (which does not exist at this server)

      Thank you very much
