I have exactly the same problem. I routinely use Hulu, Netflix, and YouTube along with my Chromecast. I've noticed that, for me, only the YouTube app causes this problem. Hulu and Netflix cast just fine. Also, it seems to happen more frequently when I've loaded videos into the YouTube app's TV Queue. (It could just be that I notice it more when managing the TV Queue because that's when I'm actively using the tablet. Otherwise I lock it, set it down, and watch the videos. I've only unlocked it once to find that the process had stopped.)
I've got a Galaxy Tab 2 8.0" running 4.4.2. I haven't been able to duplicate the issue with my Galaxy S4, so I try to remember to use that when I'm casting YouTube videos.
When it does happen on the tablet, my only option is to reboot. I've tried factory reset three times, which means I'm re-downloading the YouTube and Chromecast apps each time.
Someone in another thread on this forum mentioned that process com.android.system.ui relates to the notification bar. Thinking back to the last two times it crashed, I was swiping down to get to my notifications. Before that, I couldn't say for certain. Not sure if that's related.
