Yes, my LR CC has crashed several times while rendering previews and trying out the people stuff.
not a single crash here.
but after hours it can become VERY slugish and unresponsive.
then i have to restart LR.
my system has 32GB ram so that should be not a problem.... as LR was only using 3-6 GB.
Lots of crashes since installing LR CC (2015) on Win 8.1. Seems about every 20 minutes. And now, even though it was stable for many months, Photoshop CC crashes randomly throughout the day, too.
My laptop was totally stable until upgrading lightroom cc recently. Now lightroom crashes the whole laptop every time I use it, usually whilst editing the first photo that I wanted to amend, i.e. it takes about 3 reboots to amend even one picture.
I suspect it is an auto upload to mobile lightroom, I am going to try and disable that feature since I do not use mobile anyway.
After that, I will log a call with Adobe if it has not fixed it.
