Home server crash

We can start the server on my daughters samsung laptop and I log on the server on her laptop from my desktop through our LAN(I through cable to router and she wireless to the router), then play a little and then the console for the server, well the server, disappears(closes) and there is a crash log...

I've attached all 4 logs from the times we've tried and the server has crashed and made a log.

Please help
