Ever since I did the migration to host 75 I'm having a cpu utilization problem. Specifically, rngd is eating the cpu alive. My loads have up to the migration averaged < 0.3, since the change I'm well over 1.0.....rngd is definatly the culprit....

I'd leave it shut down, but apache starves for entropy and refuses to start....

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:
Quote:
-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.
