Error with YTD Share measure from OLAP AW in OBIEE

Question

I've created an AW using AWM 11g, created an OBIEE repository that uses it, and I'm having trouble getting a particular calculated measure to display in OBIEE.
I've created a measure called YTD_SHR_REG_PROF, which is the YTD Share of Profit for the Region, and I've included that calculated measure in my RPD file, along with Sales, Profit, and several other measures, both base and calculated.
Every other measure can be displayed in OBIEE. For example, selecting a Month and its associated Sales, YTD_Sales, and Profit works just fine. However, including my YTD_SHR_REG_PROF measure causes my Oracle Database instance to shut down. Ouch!!
Here's the wizard-generated definition of the measure:
(SHARE(UNITS_CUBE.YTD_PROFIT OF CUSTOMER.STANDARD LEVEL CUSTOMER.REGION)) * 100
I'm selecting Month, Region, Warehouse, Sales, YTD_Sales, Profit, and YTD_SHR_REG_PROF in my Answers request. If I omit YTD_SHR_REG_PROF, it works fine. If I include that measure, it stops my Oracle service.
I captured the SQL from OBIEE and executed it in SQL Developer and got the same result, shown here:
Error starting at line 1 in command:
select
T902.MONTH_LONG_DESCRIPTION as c1,
T858.REGION_LONG_DESCRIPTION as c2,
T858.WAREHOUSE_LONG_DESCRIPTI as c3,
sum(T930.SALES) as c4,
sum(T930.YTD_SALES) as c5,
sum(T930.PROFIT) as c6,
sum(T930.YTD_SHR_REG_PROF) as c7,
T902.MONTH_END_DATE as c8,

where
(T858.DIM_KEY = T930.CUSTOMER
and
T902.DIM_KEY = T930.TIME
and
T902.MONTH_LONG_DESCRIPTION = 'APR-01' )
group by
T858.CUSTOMER_REGION_ID,
T858.CUSTOMER_WAREHOUSE_ID,
T858.REGION_LONG_DESCRIPTION,
T858.WAREHOUSE_LONG_DESCRIPTI,
T902.MONTH_END_DATE,
T902.MONTH_LONG_DESCRIPTION,
T902.TIME_MONTH_ID
order by c8, c2, c3
Error at Command Line:1 Column:0
Error report:
SQL Error: Io exception: Connection reset
By the way, the measure displays just fine in AWM with View Data. The values are correct, no problems at all.
If anyone from the OLAP team is monitoring this forum, could I ask you to try to recreate this issue? I'm using the Global schema.
I was going to also post the issue in the OBIEE forum, but since the SQL bombs in SQL Developer, I don't think it's an OBIEE issue.
Thanks!

Hi Mark,
Thanks for the template.
I observe exactly the same behaviour on my local 11.1.0.7 instance. I found an error in a trace file related to a background thread ('qerfxGCol:KQFDTTIM - Error converting to LdiDateArray') but I cannot be 100% sure it is related.
Bizarrely, I found that if I strip out the sum/group_by from my query, it completes successfully and the result seems sensible
eg.
select
T902.MONTH_LONG_DESCRIPTION as c1,
T858.REGION_LONG_DESCRIPTION as c2,
T858.WAREHOUSE_LONG_DESCRIPTI as c3,
T930.SALES as c4,
T930.YTD_SALES as c5,
T930.PROFIT as c6,
T930.YTD_SHR_REG_PROF as c7,
T902.MONTH_END_DATE as c8,
T858.CUSTOMER_REGION_ID as c9,
T858.CUSTOMER_WAREHOUSE_ID as c10,
T902.TIME_MONTH_ID as c11
from
TIME_CALENDAR_VIEW T902,
CUSTOMER_STANDARD_VIEW T858,
UNITS_CUBE_VIEW T930
where
(T858.DIM_KEY = T930.CUSTOMER
and
T902.DIM_KEY = T930.TIME
and
T902.MONTH_LONG_DESCRIPTION = 'APR-01' )
I can only assume at this stage that you have uncovered a bug - is this a significant issue for you? and if so, are you able to open an SR?
Thanks,
