We are suffering majorly from the issue in this KB, and are not ready to upgrade to the fix in 6.7 u1 , in part because Veeam is not supporting it until they ship update 4.
Is it possible to execute the work around:
vim-cmd vmsvc/reload <vmid>
# Where, <vmid> is the managed object ID of the VM on the host, and can be obtained using the vim-cmd vmsvc/getallvms command.
Via PowerCLI?
Googling suggests this might work:
$VmView = $Vm | get-view
$VmView.Reload()
But others have suggested that the .reload() via powerCLI is different than a reload via vim-cmd
