Showing the image of Utilization of data collectors will be helpful for analysis. Please make sure that the Utilization of poller data collector processes indicator of the zabbix server is consistently 100%, if it is, you should adjust the StartPollers parameter of the server. You can try to adjust this parameter until the usage of the metric Utilization of poller data collector processes stays below 75%.
