      dhcp6c process CPU utilization climbs to 100% within a few minutes of a cold boot.

      Everything seems fine after I drop into a shell and kill it manually.

      Installed in KVM VM with virtIO enabled from latest ISO as of 26-Aug-2014.

      Yes, the attached screen shows ~60% - I was too lazy to wait for it again.

        Which snapshot?

        Anything from it in the DHCP log?

        Runs fine here on my VMs.

          /var/log/dhcpd.log contains a lot of:

          dhcp6c[13008]: XID mismatch
          dhcp6c[13008]: no responses were received
          dhcp6c[13008]: status code for PD-0: no prefixes
          dhcp6c[13008]: status code for NA-0: no addresses
          
          cat /etc/version.buildtime 
          Wed Aug 27 00:08:55 CDT 2014
          
          cat /etc/version.lastcommit 
          d47fac4a6ffef04e55884ada3066b532e765ba88
          

          I've replicated this on both 2.2 alpha and 2.1.4.

          Unticking the dhcp6 box within interface config solves this for me, but I'm not using ipv6.
