java.lang.NullPointerException associated w. Lutron devices

I've been seeing my Hub slow down dramatically every 3~4 days, to the point where it take ~90 seconds to go from the main screen to the list of dashboards.

Within the last 24 hours, my Hub shows 3 Error messages in the system logs, all associated with Lutron devices:
