    Missing segments on graphs

    On our Zabbix 5 server we're experiencing random interruptions in collecting data using:
    - HTTP agent: asterisk.get_stats
    - Simple check -> TCP: net.tcp.service.perf["tcp","{HOST.CONN}","{$AMI.PORT}"]
    - Simple check -> TCP: net.tcp.service["tcp","{HOST.CONN}","{$AMI.PORT}"]

    The values should be retreived every 1 minute, but in fact the graph has missing segments.
    Wireshark dump shows that the data exchange is happening NOT every minute. Zabbix doesn't send requests every minute.
    We tried changing the number of StartHTTPPollers anywhere from 1 to 10, nothing seems to change.
    Logs don't show anything relevant.
    Any ideas?
