Bad block

Hi list,

I have a situation where I'm seeing regular reports of a bad block in the
alert log.  For example :

Tue Mar 08 06:49:39 2011
Corrupt Block Found
         TSN = 24, TSNAME = XXX
         RFN = 28, BLK = 1827380, RDBA = 119267892
         OBJN = 95530, OBJD = 95530, OBJECT = SYS_LOB0000095529C00003$$,
SUBOBJECT =
         SEGMENT OWNER = XXX, SEGMENT TYPE = Lob Segment

However when I run an rman scan (validate check logical database) it is
reporting everything is fine (i.e. zero bad blocks).  The view
V$DATABASE_BLOCK_CORRUPTION
is empty.  I have tried duplicating the table (CTAS), deleting all rows and
re-populating from my copy.  No errors but still seeing the alert log
message.  I then rebuilt the Lob Segment in question with ALTER TABLE MOVE
...  Again no errors but still alert log message.

How do I fix the problem as far as whatever is reporting is concerned?

Thanks,

Steve
