CPU Usage since migration (host75)

I had the same problem until I disabled force-feeding of entropy to the random device. This may be done with the option "–feed-interval". From rngd's manual pages:
> -t n, –feed-interval=n (default: 60)

If feed-interval is not zero, rngd will

force-feed entropy to the random device even

when the entropy pool is full every feed-

interval seconds. Setting this too low may

cause rngd to dominate the contents of the

entropy pool.
