4.4.X Roms, what causes this problem topic

Every 4.4.X rom I have tried to Arc S har one problem in common, when I webbrowsing if often freezes and reboots.
I read somewhere that it is like that with all kitkat roms, but why and are there any fix or setting for it to get svolve?
I experiencing the problem happen fewer times if I dont have the websocket activated on the webbrowser, but the problem still remains.
