      Description

      zabbix_agentd didn't handle server requests correctly while multiple DNS records are used.

      It does mean that:

      • we've set the DNS record with multiple As (zabbix-servers.company.tld A 1.2.3.4, 1.2.3.5)
      • we've set the reverse DNS records for both of this IP addresses to same domain (1.2.3.4 PTR zabbix-servers.company.tld; 1.2.3.5 PTR zabbix-servers.company.tld)
      • we've set the zabbix_agentd Server option to this hostname (zabbix-servers.company.tld)

      As result, zabbix_agentd refuse several servers requests (approximately 50%, I suppose that low-level getaddr round-robin is used).
