Stephen, Thanks for the feedback. We decided to move some switches around and change some things. It appears that while we were testing we had our second box, which was not configured yet, hook to the same set of switches. It had bridging enabled causing our loop. When we migrated this box to a completed isolated environment it went away. When we added the second it happened again as expected. We made the same changes to the second node and tweak out a bunch of other stuff (to ensure that the bridge is created and destroyed during the linux HA sequence). All is good.
