For the record there is only supposed to be one row, and we do run a 
vacuum full each night, and it happened *after* this record was 

1) No. Up 377 days.
2) SCSI - configured as a hardware RAID 5 thru a LSI Logic / Symbios 
Logic 53c1010 Ultra3 SCSI  adapter

Can I now remove these two errant records or do you think there is 
anything to gain from continuing with this investigation ?

Kind regards
