Whenever restart Home Assistant, memory and CPU usage keep increase

[augiekim]

The problem

Repro step:
Settings -> System -> click icon on top right -> "Restart Home Assistant"

Expected:
Memory and CPU usages should not increase

Observation:
Memory increase by about 130MB whenever restart Home Assistant
CPU usage increase by about 0.9% whenever restart Home Assistant

It looks like the previous HomeAssistant instance is not completely closed???
