      Description

      The memory overallocate threshold is a float, so is (overAllocationThresholds.getMemoryThreshold() *
      containersMonitor.getPmemAllocatedForContainers()). Because Math.round(float) return an int, this would cap effectively the amount of memory available for overallocation to Integer.MAX_VALUE, see the code at here
