This occurs with both Docker and VirtualBox. Both applications rely on a virtual network interface, and it happens once some amount of data (estimated less than a few hundred megabytes) has been transferred over that interface. It never happens with kernel 3.13.0-29-generic, but happens all the time with 3.14.3-rt4, so obviously the kernel is the decisive factor here; how is it not regression?
