Some more.  Try executing the following command on your BSD box to see how many sockets and files (combined) you can have open at one time:

	sysctl kern.maxfilesperproc

On my Mac (a BSD box) I get around 10K.

I wonder if ECJ isn't properly closing the sockets, and so you're hitting a socket limit by repeatedly adding and removing clients.  It looks correct to me though.
