OVA failed to export - The operation is not allowed in the current state

Hello all,

I continue to receive an error when attempting to export a vm to an OVA file. I receive the following error: "Failed to export Virtual Machine: The operation is not allowed in the current state."

I was able to succesfully export 6 other vm's (all RedHat vm's) into OVA files but continue to be unsuccesful with this particular vm.

Could the size of the hard disk be the issue? Currently provisioned for 2TB.

Any thoughts?
