ORA-03113 : end-of-file on communication channel while running a SQL Query

Question

Hi,
While executing the following query, we are facing ORA-03113 : EOF on communication channel error.
SELECT
FROM QDF_CLSS_SHENG_HIST
/*WHERE* a.FACT_TYPE_CODE='BS'
AND */
WHERE (SRCE_SYS_ID = 850 OR (SRCE_SYS_ID IN (1747,1764) AND GEO_ID IN (826,372) AND PRTTN_BY_FUNC_DATE>=to_date('20060701','YYYYMMDD') ))
When we remove one of the values in the SRCE_SYS_ID's 'IN' condition the error is not thrown, e.g.
WHERE (SRCE_SYS_ID = 850 OR (SRCE_SYS_ID IN (1747) AND GEO_ID IN (826,372) AND PRTTN_BY_FUNC_DATE>=to_date('20060701','YYYYMMDD') ))
The version of the Database we are using is 10.2.0.3.0 - 64bi. Is this a common error in this version of the database because when we ran the same query in a 9i database we got no such error.
P.S : QDF_CLSS_SHENG_HIST table is partitioned on SRCE_SYS_ID and PRTTN_BY_FUNC_DATE
Thanks,
Puneeth

Yes, we get the same error and no dumps are getting created.It might be interesting to look at a trace file for this SQL statement with event 10046 at level 12 and event 10053 at level 1 enabled for the session. You may need to modify the query slightly to make certain that a hard parse is required (possibly by specifying a couple of the column names to be returned rather than *). Take a look through the raw trace file for something like this
cost: -1.#IND  card: 1.#INFThere is at least one query in the ERP package that I use that will output the following in a 10053 trace when optimizer_features_enable is greater than 10.1.0.4, followed by an ORA-600:
