Dear Phillip, X-Air and WeatherCat endurance runners,
It crashed today. I think it was running for 130 days....
Bummer dude!
It is now time to upgrade to High Sierra and WC 2.4.4.
Well, WeatherCat 2.4.4 is a safe bet. However with two root exploits managing to sneak through of High Sierra beta testing, perhaps you should let that version of macOS
"simmer" for another 130 days before risking it.
Cheers, Edouard
