Hubitat Locks up

I figured out my issue I think. One night I noticed in the log that Alexa App was going NUTS (Builtin not the TTS). There were tons of throttling mesages from Amazon and my hub voice announcements were getting slow. I think I had Alexa Echo App not Alexa Echo Skill. I had always wanted to upgrade, but hadn't ever seen the option to install Alexa Echo Skill. Well I deleted the Alexa Echo App, and when I went to reinstall I saw the Alexa Echo Skill and instead installed it. I also pruned the list of allowed devices down to 20ish. Ever since then I've been a OK. My Alexa view of my house via the app is also more responsive.
