smartctl_type causes CPU spikes on unraid 6.12.8

Hello!

 

I have an annoyance / issue where each ~30s I get a CPU spike.

Looks to be from the smartctl_type processes (which I understand they are related to SMART).


Any idea what exactly makes smartctl_type cause the spikes and how to stop it? (or at least, have the processes run once 30m not 30s)
This has been ongoing since the day I installed unraid. I have only 2 apps, Community Applications and Compose.Manager.

Thanks!

UPDATE:
looks like php smartctl_type process does not properly shut down, we see some zombie processes.

The short-medium term fix I found was to simply rename the smartctl_type script to something else so it wouldn't get triggered anymore

Still no idea what triggers it thought
This is the before and after:
