    Sudden jump of Zabbix busy poller processes after server reboot

    I have experienced very weird problem, after Zabbix server reboot Zabbix busy poller processes went to 100% from under 20% (stable). After changing pollers from 100 to 150, it dropped a bit over 20%, but still staid high.



    It is a very small environment so I am wondering what exactly could cause this.

    Zabbix server is running Yes
    Number of hosts (monitored/not monitored/templates) 75 44 / 5 / 26
    Number of items (monitored/disabled/not supported) 1678 1421 / 189 / 68
    Number of triggers (enabled/disabled) [problem/ok] 299 297 / 2 [1 / 296]
    Number of users (online) 6 2
    Required server performance, new values per second 25.76 -

          Got this resolved, turned out to be DNS server issue.

          DNS server screwed up at the outage time and we even didn't notice that it didn't serve all records as it's a backup physical DC that is not being used by clients. Restart of DNS server helped to resolve issue, back to normal.

          At no moment I thought that this could be a DNS thing...
