So this started out as a Veeam issue. It was working fine, then all the sudden backups were failing because of a connection problem with vCenter. Exact error from Veeam below when trying to rescan vCenter.
6/19/2014 12:51:27 PM Error Disks and volumes discovery for VMware vCenter 'lga1vcs01' failed Error: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.
6/19/2014 12:51:27 PM Error Host discovery failed Error: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.
Even when Veeam does connect and start the backup, sometimes it fails at hot adding the VMDK to the Veeam proxy.
Here are a couple of screen shots when using the vSphere Client. As you can see it is trying to load the information, but often times takes awhile to populate or doesn't populate at all.
Based on that I would think it is vCenter having trouble communicating with the ESXi hosts. But I also do have issues with the Update Manager getting stuck at checking for updates. I've also noticed issues in the Web Client with suppressing alarms and it hangs. Again sounds like a communication problem with the host.
When I manage the ESXi servers directly through the vSphere Client, everything seems to work fine.
