To reproduce, bring up a development Trafodion instance and create a table with a little data in it. Then in the sql/scripts directory, execute the "rmsstop" script to stop RMS. (Note: You can restart it again later if you wish using "rmsstart".) Then, while RMS is stopped, issue an UPDATE STATISTICS statement.
