Keith, 
        thanks a lot.
        So I was right, they do go to alert log in 9 or a least some 9s.

What's difference between 
event="1555 trace name errorstack level 3"
and
event="1555 trace name errorstack level 5"  ?

        isn't that usually important?

        We changed from 2 to 12 on
#event  = "10235 trace name context forever, level 12"  #TAR 3030722.995
and Batch jobs ran 10% slower

        Thanks
        Larry

Well, we just upgraded from Oracle 8 to 9i (finally) and started getting
them. We do not have any of the events set, except the "4031"
