create index online

Hi all, I created a new index ONLINE. Thought that would cause no problems in production. However, one program reported errors: > Program stopped at "/home/projekte/p3_neu/lib/f_vo_upd.4gl", line number > 464. > Date: 04.11.2009 Time: 18:51:54 > > Program error at "/home/projekte/p3_neu/lib/f_vo_upd.4gl", line number > 464. > SQL statement error number -710. > > Table (informix.ap_da_v1) has been dropped, altered or renamed. > > SYSTEM error number -21523. > > Cannot proceed with a dirty/modified table data dictionary entry. > > SQL statement error number -710. > > Table (informix.ap_da_v1) has been dropped, altered or renamed. > > SYSTEM error number -21523. > > Cannot proceed with a dirty/modified table data dictionary entry. > > Version of IDS is 11.50.FC5. Is this a bug or did I understand something wrong? TIA, Reinhard.
