System Report odd message

I just wonder if anyone knows what in the world this means:

Endpoint has been activated through legacy launch(3) APIs. Please switch to XPC or bootstrap_check_in(): com.apple.CoreRAID

Is it because my iMac getting old? Moisture in it from steaming in a Harvey flooded house for 9 days?

I think that next year it will be going onto Apple's Legacy Trash Heap.

I just reinstalled High Sierra.
