On iOS 11.4.1 my iCloud Photos Library of ~60k photos never finishes generating the faces album. The device logs show that photoanalysisd is being killed by the kernel for memory violation after only a few minutes of phone locked on charger. I have left my phone locked and on charger overnight each night for the last 6 weeks.

The faces album reads:

Updating People...
To finish updating your people, lock your iPhone and connect it to power.
