Issue

After upgrading OnCommand Unified Manager, the available space in "/data" or your Windows install directory began to decrease abnormally fast over time. In the example below the "/data" filesystem is 93% used. This rapid usage increase in Unified Manager is precursored by a upgrade of Unified Manager 6.x to Unified Manager 7.x.
