    CAUSE

    The cause of this problem has been identified in 
    Bug 7429941 - ORA-00600[KCBZ_CHECK_OBJD_TYP_1] SOMETIMES OCCURS 
    closed as duplicate of unpublished Bug 4430244 and related to unpublished Bug 5218905.

    Unpublished Bug 4430244 is caused by the Segment advisor code that can load blocks into the cache for DROPped objects as CURRENT leading to subsequent operations seeing an incorrect (old) version of a block.

    Unpublished Bug 5218905 can occur when segment advisor has been running on an instance as it can read blocks into the cache as CURRENT when it should have read them as CR.

    Both unpublished base bug 4430244 and related unpublished Bug 5218905 are a.o. fixed in 11.1.0.6 (Base Release) and 10.2.0.4 (Server Patch Set).
