SYSINDEXES IN INDEX WITH FOT

product:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problem description:
Consider a large table with 600 Mio rows and on this table there
is a FOT index
created on a serial column with unique values. When an update

on this table/index is made and USTLOW_SAMPLE is set to 1, every
second run
on this update statistics returns -1223 on selects on
sysfragments and sysindexes

use the FOT index as
the access path, it may return an -768 during the optimization
