Haveged on ReadyNas Ultra ?
I am running LMS (squeezebox) on my readynas ultra. There is a problem with the Random mix. The problem is that it isn't very random. The problem could be this that I have read about: http://www.i...

Andwatch -n 1 cat /proc/sys/kernel/random/entropy_availgives me low values too.
Wonder why I had high values before...
If nothing is using dev/random or dev/urandom, the entropy pool gradually fills. Presumably, your system wasn't doing much that needed random numbers, so the pool filled to 2000+ bits.
Every time a new process is launched, the operating system reads from dev/urandom in order to randomize the process's address space layout (to protect from buffer overflow attacks), so when you repeatedly invoked cat once per second with that watch command, the available entropy decreased faster than it could be replenished.
