I'm trying to help out my university troubleshoot it's problem

"too many open network connections" determined exactly how?

However, a netstat command from OSX's Network Utility reports that an
average OSX machine connected (only wirelessly) has anywhere between
10,000-20,000 connections. Here's an example printout:

That smells mightily wrong.

136087 packets sent

220755 packets received

That's historical, not current.

! --> 11919 connections established (including accepts)
12267 connections closed (including 29 drops)

man netstat - in a normal *nix, '/bin/netstat -tuan' should tell what
is _currently_ in use.

This number doesn't seem to be dependent on what programs/utilities are
currently using network resources, as closing programs like iTunes and
Safari don't affect any change (often, the number increases).

which sounds like a historic (cumulative) count, rather than a current
(now in use) count.

There isn't a sanctioned big-eight newsgroup for OSX, but you are posting
from googlegroups - why not search there for such a group. The server I'm
using (giganews) has several, or you could always look in
comp.unix.bsd.freebsd.misc.
