Google sitemaps 3.1.2

When I upgraded to 3.1.2 my the plugin stopped generating sitemaps correctly. Also, when posting a new post or editing and save an old one, I just get a blank page instead of being returned to the post after save.

It seems the sitemap plugin runs out of memory.

Other plugins used: Adman, Adsense manager, Aksimet, All in one SEO, Category post, Configurable Tag Cloud, Embedded vidoe, Google analyticator, Insights, Official Statcounter, Simple Feed Copyright, Wassup, Sociable, WP Postviews and WP Ajax Edit Comments.

Any ideas? I have had to disable Google sitemaps, and that sucks big time!
