Casual "more than 4,294,967,296 tuples" errors upon query to ROLAP cube

Question

With SSAS 2008R2 SP2 CU12 I observe the behavior that looks weird to me and I'd be very thankful for explanation or help with this problem as long as this issue is experienced by our customer and it has critical status now. Fortunately, I was able to reproduce
this in lab environment, so I've pretty much details.
I have an independent process that constantly adds facts and members to relational tables that are used in ROLAP cube and dimensions.
I have MDX query like this:
SELECT
  NON EMPTY
    {[Measures].[MyPhysicalMeasure1]} ON COLUMNS
 ,NON EMPTY  
        [MyDim1].[MyDim1].[MyDim1].ALLMEMBERS*
        [MyDim2].[MyDim2].[MyDim2].ALLMEMBERS*
        [MyDim3].[MyDim3].[MyDim3].ALLMEMBERS*
        [MyDim4].[MyDim4].[MyDim4].ALLMEMBERS*
        [MyCalendarDim5].[MyCalendarDim5].[Minute].ALLMEMBERS*
        [MyDim6].[MyDim6].[MyDim6].ALLMEMBERS*
        [MyDim7].[MyDim7].[MyDim7].ALLMEMBERS*
        [MyDim8].[MyDim8].[MyDim8].ALLMEMBERS*
        [MyDim9].[MyDim9].[MyDim9].ALLMEMBERS*
        [MyDim10].[MyDim10].[MyDim10].ALLMEMBERS*
        [MyDim11].[MyDim11].[MyDim11].ALLMEMBERS
  DIMENSION PROPERTIES
    MEMBER_CAPTION
   ,MEMBER_UNIQUE_NAME
   ON ROWS
FROM
  SELECT
    [MyCalendarDimNamedSet_12Months] ON COLUMNS
  FROM
    SELECT
      StrToSet
      ("[MyDim12].[MyDim12].&[MyMember1].&[MyMember11]"
       ,CONSTRAINED
      ) ON COLUMNS
    FROM [MyROLAPCube1]
CELL PROPERTIES
  VALUE
 ,BACK_COLOR
 ,FORE_COLOR
 ,FORMATTED_VALUE
 ,FORMAT_STRING
 ,FONT_NAME
 ,FONT_SIZE
 ,FONT_FLAGS;
So, here is scenario:
1) If I run this query for a 1st time I'm getting the error:
"The expression contains a function that cannot operate on a set with more than 4,294,967,296 tuples."
2) If I keep the process that adds facts and members running I'm constantly getting the same error on attempt to execute MDX:
"The expression contains a function that cannot operate on a set with more than 4,294,967,296 tuples."
3) If I stop the process that adds facts and members and wait for few seconds, the query will be successfully executed!
4) If I keep the process that adds facts and members stopped, the query will be successfully executed at any time.
5) If I keep the process that adds facts and members stopped, reconnect client, the query will be successfully executed at any time.
6) If I keep the process that adds facts and members stopped, restart SSAS and reconnect client, the query will be successfully executed at any time.
7) If I resume the process that adds facts and members, wait for few seconds, the query will fail with the same error:
"The expression contains a function that cannot operate on a set with more than 4,294,967,296 tuples."
I have already tried replacing the NON EMPTY with NonEmpty function, as some articles suggest - no luck, results will be the same.
I'd be very thankful for explanation or any help with this problem!
Thanks!

Hi Andrei,
The error “The expression contains a function that cannot operate on a set with more than 4,294,967,296 tuples” was described on the link
http://support.microsoft.com/kb/2430162
And it said that it was fixed in the Cumulative update package 2 for SQL Server 2008 Service Pack 2, however, you have applied CU 12 in your environment and still can reproduce this error. So I am afraid this issue can occurs on some particular condition.
So I recommend you submit a feedback at
http://connect.microsoft.com/SQLServer/Feedback and hope it is released in the next release of service pack or product. Your feedback enables Microsoft to make software and services the best that they can be, Microsoft might consider to add this feature
in the following release after official confirmation.
We appreciate your comprehension.
