Help with dbexport

I have a dbexport from Informix Turbo crashing out with a memory allocation error. It only happens on one table, the largest approx 18 GB, most of which is blob data. I also have all 32 chunks in use and can't allocate anymore (known Turbo bug) A truss output for the export confirms that there is a ENOMEM error being produced at a brk() call in the code. I believe I've tried all the obvious things eg Added 256 MB RAM to the box (originally 128) Up'd SHMMAX from 512000 (ish) to 4096000 (ish) Up'd ULIMIT from 64000 (ish) to 1000000 (ish) No errors are being reported in the message areas both for Unix and Informix. BTW the export needs to be done at the weekend so the data can be reorganised or else the site will be out of space by Monday. Anybody got any ideas, and yes I know that nobody anywhere still uses Turbo 'cos its *@*(!!.
