Thrashing with C2G - what to do?

I have a 2.4Ghz 6Gb 64-bit machine running Gimp 2.6.7 on Mandriva Linux 2009 Spring. The Tile Cache Size is set to 5Gb.

A 31MB tiff file is converted by c2g pretty quickly. However a 45Mb tiff converts about half the preview image quickly and then halts indefinitely, thrashing with the CPU 100% occupied. I've run gimp in verbose mode on a succesful and this unsuccessful conversion - there's nothing obviously different in the messages, except that the unsuccessful conversion seems to be hung at an earlier stage.

What's up? Is it likely that c2g would saturate 5GB of memory with a 45Mb image?
Are my adjustments wrong? Or is there some other way round this?
