INTERESTING: ORA-00600: internal error code,

Question

Here is the scenario:
DB1 = 11.2.0.1.0 Linux 5
DB2 = 11.2.0.1.0 Linux 5
Init.ora on DB1 and DB2 are exactly the same.
On DB1, I run this and get ORA-600:
select distinct i.short_desc,c.short_desc, c.long_desc
from pace_masterdbo.codes c, pace_masterdbo.code_values cv, pace_masterdbo.interfaces i
where C.INSTANCE=CV.CODE_INST
and CV.INTFC_INST=I.INSTANCE 2 3 4
5 /
from pace_masterdbo.codes c, pace_masterdbo.code_values cv, pace_masterdbo.interfaces i
ERROR at line 2:
ORA-00600: internal error code, arguments: [qkaffsindex5], [], [], [], [], [], [], [], [], [], [], []
On DB2, with the same configuration and exact init.ora parameters it works without issue.
Now on DB1 if I change the following, it works fine, wondering what's going on.
alter session set "_optimizer_cost_based_transformation" =off;
Session altered.
select distinct i.short_desc,c.short_desc, c.long_desc
from pace_masterdbo.codes c, pace_masterdbo.code_values cv, pace_masterdbo.interfaces i
where C.INSTANCE=CV.CODE_INST
and CV.INTFC_INST=I.INSTANCE 2 3 4
5 /
NOW WORKS FINE.. ANY IDEA???
Thanks in Advance..
