Burn Lewis resolved UIMA-5605.
------------------------------
Resolution: Fixed
Fixed error in setting free space when a machine size changes. This problem
was more likely to occur when using the default quantum of 1GB as small changes
in memory used by "system" processes might change DUCC's count of available
shares on the machine.
