high cpu usage reported after couchbase server 2.0 installation ( errors when before_header,after_header,on_file_open)

from prospect:

I just installed the 2.0 beta and with 2 nodes, CentOS 6.3, 64-bit and nothing talking to CB
top reports:

I'm at a loss to understand over 300% cpu usage when I only have the default bucket
and it's empty. The same is true on the other node in the cluster.

I restarted both servers in the cluster and brought them back up....same thing, ~300% cpu on both servers
with no clients attached. These nodes are the same exact hardware and are located in the same physical
chassis (Dell C6105)
