DBExport needs temporary Files ?

Hi all, my IDS.9.3 Server (Sun E250 with Soliaris 5.9) is uses as a replaction server for informix, so i can make some dbexport's for all DB's. This worked very fine the last few months. Since a few day's i have got this message : -229 - Could not open or create a temporary file. -140 - ISAM error: operation illegal on a DR Secondary This happes after the 'Grants' - Commands for the stored procedures, before the first table will be exported. So my question is a) why does IFX use a temporary file (or Tempspace which i use) during a dbexport ? b) how could i avoid this error ? kind regards from hamburg Sven
