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
inserted.
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
Rob
