Hi, John:

I followed your suggestions. Also, I separated the Kunena categories and topics so that that two separate datasets/sitemaps could be created. I can build the Kunena categories sitemap fine but the Kunena topics are the problem and they abort at the same point.

BTW, I have already built split sitemaps several times for our JReviews content of 664,000+ listings with the precaching limit set as high as 50,000. That uses less than 10% of our server memory -- although it uses a lot of CPU. So memory issues don't seem to be the problem.

So what to try next?

Thanks. -- Rik
