Data Space auto expand

Hi, I had problems uploading large (>10 MB) nonXML files with the NonXMLIndexer to my tamino Database. After a while I found out that the allocated data space for the database was almost full (180 MB of total 185 MB used), so the 10 MB file couldn’t not been uploaded. After I expanded the dataspace of 100 MB, the upload was succesfull. However the auto expand property for the database was set to yes. It seems that tamino does not expand the dataspase for nonXML files. Is this a bug, known issue? thanks, Simon
