We have a category with around 12,000 products and when I try and save it, the page just spins for a few minutes then I get an internal server error.
The errors are connection is reset or timeout errors. But I can't imagine that it should take this long to save the category.
Update to this. It seems to time out with any category we have tested so far with at least 4000 products. It doesn't even have to be a category with 4000 direct products, even a category that has sub-categories with products totaling 4000+ won't save. The default category will save though, which is odd.
Has no one else had this issue?
