PLEASE HELP! Two Subcategories Won't Display Products on Listing Page?

For some reason, two of my sub-categories won't display their product listings on their product listing page. The page basically stops where the product listing is supposed to start. No error. Nothing in the log. Only two (out of 26) categories are doing this. The products display correctly in the admin site. Any ideas? Please help! Thank you!

BTW, I switched to the default template in the admin site and see the same problem on those two subcategory pages. Database related? How would I go about fixing?

Any ideas? Sorry guys -- I just need to resolve this ASAP. Any ideas on first steps? Think it might be database-related?

A link to your site would be really helpful.

I found the problem. Went through the two subcategories and moved products out one at a time until I found the culprits. Then deleted and recreated the products. I assume it was a database issue. Very odd.
