Hi.

Just reporting I don't know if this is a bug or just a configuration issue.

I've recently upgraded a small test box from 5.0.4 to 5.2.0 and noticed that pollers are busier after receiving "Zabbix poller processes more than 75% busy" alerts.

I use the default config from zabbix_server.

System information:

Parameter | Value | Details
---------------------------
Zabbix server is running | Yes | localhost:10051
Number of hosts (enabled/disabled) | 6 | 5/1
Number of templates | 85 |
Number of items (enabled/disabled/not supported) | 1483 | 751/31/701
Number of triggers (enabled/disabled [problem/ok]) | 559 | 534/25[2/532]
Number of users (online) | 7 | 1
Required server performance, new values per second | 18.05

The utilization went down after double the initial value of StartPollers, from 5 to 10.
Zabbix data gathering process busy graph is attached.

Regards.
