I'm getting 0 primes per sec even though the CPU usage is near 100%. I'm running Ubuntu 12.

All I did was
1. Set rpc user and password in .conf file.
2. run "./primecoind -daemon"
3. run "./primecoind -setgenerate true 8"

Then when I run "./primecoind getmininginfo", it says my primespersec is 0 even though CPU is being used.

Can someone help me?
