Deleting a chunk in rootdbs

Hi all, I'm working as a consultant in some "strange" system. The rootdbspace has 3 chunks and the On-Line system, more than 20 databases. I've dropped all the databases except sysmaster and sysutils and deleted the other dbspaces with no problem. The 3rd chunk of the rootdbs is deleted too, but the second no. Informix says that it isn't empty. I've moved the physical logs to other dbspace, dropped all logical logs until reach the limit of 3. My system has 2 databases, a dbspace with physical log and temporary area and a 2-chunk in rootdbs. How can I delete the 'rest' of the data in the second chunk of the dbspace? About 500 pages are in use in it... Thanks and forgive English errors please... I'm from Brazil! []ao LEO Cardoso ---
