Yes, after installing mod_perl (which is supposed to work with UBB 6), the stats files for the larger forums (PowerMac, OS X Gen, and the Lounge) have been corrupting several times a day, so you only see a few threads.
If the stats files are corrupted, most likely I'll know about it within 15 minutes or so and fix it.
It's a real PITA, but we've called up Infopop and hopefully they'll get back to us soon with a solution.
