APN01_CPU is a Zabbix item that monitors CPU utilization by the AP. APN01 refers to a Ruckus AP model ZF7341.

On 07/21/2019, with no device connected, the item trigger was triggered after detecting that more than 80% of the CPU was being used.

What may have led to this high utilization?

You need to analyze the AP's 'Support Info' file. An AP and controller send infrequent RRM updates, for example, beside just client traffic.
