doimport with blobdata fails on TD5 on terminal server

I have installed informix 7.31 TD5 on a terminal server. Before we used other versions. Now import fails when importscript reaches part with blob-data. Import just stops with message "Archive to tape device 'nul' is complete. Program over." The part that fails is like below: { TABLE "informix".doc_data row size = 155 number of columns = 11 index size = 30 } { unload file name = doc_d00131.unl number of rows = 1324 } create table "informix".doc_data ( dd_sequence serial not null , dd_type integer, dd_data byte in blob1, dd_name nchar(64), dd_usage smallint default 0 not null , dd_compressed nchar(1), dd_original_size integer, dd_scanner smallint, dd_scan_time datetime year to second default current year to second, dd_authorizer smallint, dd_authorize_time datetime year to second ); -- Direct access to this group with http://web2news.com http://web2news.com/?comp.databases.informix To contact in private, remove nno-5spp+5am
