I'm no switch expert, but your last comment caused an hypothesis to pop
into mind. Do any of your hosts have hard-coded MAC addresses set up?
This isn't common, but if you're trying to prevent ARP poisoning, one
might do this. If you were to do this, and not tell the switch which
ports had those MACs, then it wouldn't get a chance to learn those MACs
since those hosts wouldn't bother sending ARP requests, right? Just a
thought.
