Cannot read system catalog (systables). key value

The application is pointing me to the link below which discusses update statistics. Is it normal that we should perform stats on the catalog database(s). I've never thought to do that nor have I not seen it done. Should I perform a low, medium, or high? APPLICATION: I found a post on the web that refers to this error and how someone fixed it. I recommend you schedule update statistics processes to whole database tables using criteria levels recommended by Informix and also run update statistics for its procedures, but you should take off the tables from you daily update statistics process which are being referenced inside stored procedures. Here is the post. http://www.iiug.org/forums/ids/index.cgi/noframes/read/1566 It looks like this is an Informix bug (bug # 173595) that has been fixed in Informix 10.00.xC9E.
