I have a vcenter 5 server with 5 clusters configured. One cluster has 3 hosts. They all use the same vDs for all activities including vmotion. 1 host continually drops the vmotion network. I have rebuilt this host and the issue remains. All hosts are built on UCS using the same profile template. I have moved the profile to different blades and to different chassis' and the problem remains. It appears that the network ports are flapping on this host.
