UserParameter being called more than once per period.

Hello,

I've configured a Zabbix UserParameter to call a Powershell Script in a Windows Agent Configuration File.
This powershell script is configured to send data to Zabbix via Zabbix_Sender and it seems to run fine when it's called using zabbix_get.

I've tried then to configure a Zabbix Item (let's call it item 1) to get data from that UserParameter each hour.
It calls the script and collects data as expected, but the item (another, item 2) that should receive the data from Zabbix_Sender, receives two (and sometimes three) entries as if the Powershell Script were being executed multiple times.

The strangest thing is that the timestamps I see in the spares entries are seconds or even minutes BEFORE the time the script should be triggered (as registered in the UserParameter Item (item 1)).

Does anybody know what could be causing this behavior?

Regards,

I've troubleshooted some more and discovered that two separated pollers tries to get the requested information. Does anybody knows what process is responsible to enqueue the poller requests?
