In my experience, it always works, but you might end up with a unresponsive
system for minutes/hours/days, because it swaps out the memory (if you have
enough), which is in the way. I killed at least two machines with this.
Therefore, I always configure hugepages and do a reboot. This way I will
not end up in a totally messed up system.
