MDX Query causing Operation Cancelled due to Memory Pressure

Am facing Memory Pressure issue when I execute the following MDX Query. 

WITH 
  MEMBER [Measures].[Entity1] AS 
    [Provider].[Provider Name].CurrentMember.Member_Caption 
  MEMBER [Measures].[Entity2] AS 
    [Dim Date].[Calendar Date].CurrentMember.Member_Caption 
  MEMBER [Measures].[Entity3] AS 
    [Dim Type].[Type Name].CurrentMember.Member_Caption 
  MEMBER [Measures].[Entity4] AS 
    [Dim Device].[Device_Id].CurrentMember.Member_Caption 
SELECT 
  NON EMPTY 
    {
      [Measures].[Amount-Exception]
     ,[Measures].[Exception Count]
     ,[Measures].[Entity1]
     ,[Measures].[Entity2]
     ,[Measures].[Entity3]
     ,[Measures].[Entity4]
    } ON COLUMNS
 ,Filter
  (
    (
      {
        [Provider].[Provider Name].[ALL].Children
      }
     ,{
        [Dim Date].[Calendar Date].[ALL].Children
      }
     ,{
        [Dim Type].[Type Name].[ALL].Children
      }
     ,{
        [Dim Device].[Device_Id].[All].Children
      }
    )
   ,
      [Measures].[Amount-Exception] <> NULL
    OR 
      [Measures].[Exception Count] <> NULL
  ) ON ROWS
FROM 
(
  SELECT 
    {
        {[Provider].[Provider ID].[All]}*
        {[Fare Type].[Fare Type Id].[All]}*
        {[Dim Authority].[Authority Id].[All]}*
        {[Dim Type].[Type Id].[All]}*
        {
              {
                  {
                      [Dim Date].[Calendar Date].[2011-08-07]
                    : 
                      [Dim Date].[Calendar Date].[2012-08-05]
                  }
                * 
                  {[Dim Time].[Time Key].[ALL]}
              }
            + 
              {
                  {[Dim Date].[Calendar Date].[2011-08-06]}
                * 
                  {
                      [Dim Time].[Time Key].[10:40:26.000000]
                    : NULL
                  }
              }
          + 
            {
                {[Dim Date].[Calendar Date].[2012-08-06]}
              * 
                {NULL
                  : 
                    [Dim Time].[Time Key].[10:40:26.000000]
                }
            }
        }
        
    } ON 0
  FROM [ProviderCube]
);

On disabling the Time part of the query, the query works fine i.e. the below query -

WITH 
  MEMBER [Measures].[Entity1] AS 
    [Provider].[Provider Name].CurrentMember.Member_Caption 
  MEMBER [Measures].[Entity2] AS 
    [Dim Date].[Calendar Date].CurrentMember.Member_Caption 
  MEMBER [Measures].[Entity3] AS 
    [Dim Type].[Type Name].CurrentMember.Member_Caption 
  MEMBER [Measures].[Entity4] AS 
    [Dim Device].[Device_Id].CurrentMember.Member_Caption 
SELECT 
  NON EMPTY 
    {
      [Measures].[Amount-Exception]
     ,[Measures].[Exception Count]
     ,[Measures].[Entity1]
     ,[Measures].[Entity2]
     ,[Measures].[Entity3]
     ,[Measures].[Entity4]
    } ON COLUMNS
 ,Filter
  (
    (
      {
        [Provider].[Provider Name].[ALL].Children
      }
     ,{
        [Dim Date].[Calendar Date].[ALL].Children
      }
     ,{
        [Dim Type].[Type Name].[ALL].Children
      }
     ,{
        [Dim Device].[Device_Id].[All].Children
      }
    )
   ,
      [Measures].[Amount-Exception] <> NULL
    OR 
      [Measures].[Exception Count] <> NULL
  ) ON ROWS
FROM 
(
  SELECT 
    {
        {[Provider].[Provider ID].[All]}*
        {[Fare Type].[Fare Type Id].[All]}*
        {[Dim Authority].[Authority Id].[All]}*
        {[Dim Type].[Type Id].[All]}*
        {
              {
                  {
                      [Dim Date].[Calendar Date].[2011-08-07]
                    : 
                      [Dim Date].[Calendar Date].[2012-08-05]
                  }
                * 
                  {[Dim Time].[Time Key].[ALL]}
              }
        }
        
    } ON 0
  FROM [ProviderCube]
);

Putting the Dim Time is causing the memory issue. The facts to which these dimensions are bound are set to Automatic for processing. What could be the problem?
