And that's doubtless not from TCP port issues but because of other
kinds of resources being limited.

Sometimes that's reasonable. I've seen large sites where everyone has
a workstation in front of them and all of the thousands of users get
their home dir automounted when they sit in front of a box and log
in. However, one notes that in such a situation, the automount maps
have thousands or tens of thousands of entries, but any given machine
generally only is mounting a few file systems.
