Oracle ORA-00600

Question

I have SQL SELECT statement that returns:

    Error: ORA-00600: internal error code, arguments: [qerpfAllocateR], [], [], [], [], [], [], []

If I narrow my results by adding one more condition in WHERE clause everything is ok.

Anyone knows what is happening?

EDIT:

    select * from ( select tbl1.col1, ..., tbl1.points
    from table1 tbl1, table2 tbl2
    where tbl1.tbl2FK = tbl2.PK and
          tbl2.col1 = someNumber and
          tbl1.dateColumn = to_date('27-10-2008','dd-mm-yyyy')
    order by tbl1.points desc ) s where rownum <= 3 

EDIT2:

My DB admin suggested solution that works:

select * from (select rank() over (order by tbl1.points desc) rank,
                  tbl1.col1, ..., tbl1.points
           from table1 tbl1, table2 tbl2
           where tbl1.tbl2FK = tbl2.PK and
                 tbl2.col1 = someNumber and
                 tbl1.dateColumn = to_date('27-10-2008','dd-mm-yyyy')) s
     where s.rank <= 3

The ORA-0600 error indicates an internal error in Oracle itself. You're most likely hitting an Oracle bug.

If you go to http://metalink.oracle.com, you can look up the exact bug, if it is known, by pasting the "arguments" and full stack trace into the ORA-0600 lookup tool. See metalink note 153788.1.

If there's a known bug with that description, it's likely that there's already a patch available for you to download and install. If it's not a known bug, contact support.
