Attempting to create a VM with more than 20 GB of Memory fails due to illegal memory size

Solution Verified - Updated 2013-06-02T01:25:18+00:00 -

Issue

When I attempt to create a VM via the Administrator Portal or via the API I am getting a message that states:

API:

[Cannot add VM. Illegal memory size is provided, size needs to be between 256 MB and 20480 MB.]
UI: I manually enter a memory size of 123456 MB and press 'OK'. The Memory Size field is highlighted orange and when you hover over a message is displayed:

Maximum memory size is 20480MB
