Abstract : ORA-600: INTERNAL ERROR CODE, ARGUMENTS: [KCBNEW_3]
Versions affected : 10.2
Fixed releases : 10.2.0.4, 11.0.0.0
Details : Segment advisor code (eg: DBMS_SPACE.OBJECT_GROWTH_TREND)

This can lead to various internal buffer cache related errors such as
ORA-600 [kcbnew_3] / ORA-600 [kcbz_check_objd_typ_3].
The exact error depends on which code sees the block.
Backportable : yes to 10.2
Symptoms :
1. ORA-600 [kcbnew_3] internal error reported in the alert.log
2. May occur if segment advisor and DROP operation are being run
concurrently on the same object.
