Thanks Stefan, I think that is the answer I was looking for - I think your SQL is deleting ways etc. that do not refer to existing nodes in the db? I will give it a go, and see if my poor little virtual machine can cope - it is certainly struggling now the database has got so big.
Would you mind if I added a link from the minutely Mapnik page to your solution? Regards Graham.
