dostats error

Hi, with the command dostats -d database --f file after a couple of successful actions appears the following error: FAILED: Cannot FETCH table data (a1). SQLCODE = -1215, ISAM = 0. Statement is: SELECT a.tabid, a.partnum, a.nrows, a.tabname, a.owner,indexkeyarray_out(b.indexkeys) AS allparts, 0 FROM "informix".systables a, outer ("informix".sysindices b, outer "informix".sysobjstate s) WHERE a.tabid = b.tabid AND tabtype = 'T' AND a.tabid >= 100 AND a.tabid = s.tabid AND s.objtype = 'I' AND b.idxname = s.name AND s.state != 'D' ORDER BY 1, 3, 4, 5; dostats: Features Version 5.10, Source Revision: 1.137 !

IDS 11.50.FC3, Solaris 9 The command was successful before I did "update statistics medium for table" and "update statistcs for procedure". And I killed an update stats job not sure what he did in that moment. The query above works without an error in dbaccess. Any ideas what causes the error? Regards, Reinhard
