Every once in a while on our site (at least once a week) random products will pop up in the cart block not put there by the customers. The cart block is also viewable to anyone who visits the site (not logged in), listing these random items in their cart. If you log in however, the cart goes empty. It's weird, and I would assume off putting to our customers.
Our IT guy thinks the block is showing what an anonymous customer put in their cart, but did not buy. Then that information somehow gets put universally in everyone's cart block, thus confusing other customers. We clear the cache, and that sweeps it out, but this is of course after the problem has occurred.
Anyone seen this before, or have an idea of how to deal with it?
