@danabw You know me... I need some data to go off of or at least some sort of hint... Been running 224 as long as you and not experiencing any of the issues you describe. Maybe run hub stats? Check the hub memory?
http://hubitat.local/hub/enableStats (Run this to start stat collection and let it collect for about 5 minutes)
http://hubitat.local/hub/stats (Run this after the 5 minutes has elapsed to view the stats)
http://hubitat.local/hub/disableStats (Run this to stop stat collection)
For Winodws PC's Shift + Windows Key + S is an easy way to take a cropped screenshot.
You can use these links to track down the apps and devices by putting the id's from stats

Hub Memory

If nothing shows up do a safe shutdown and power pull and see if the problem comes back.
