i have my tftp daemon started by inetd and it then kills itself after a
certain period of inactivity which would fix the problem you're having of
having lots of them open...
if that helps?

FWIW:
I experienced the same scenario a couple of weeks ago. My sysload
gradually
grew to over 150 (!!!), now that is slow.
It turned out that one client was buggy in its PXE loader. It kept asking
and
initiating a tftp load, then gave up. And tried again and again and
again...
Al the ftfp processes somehow kept running - all owned by "nobody" - and
eventually would cause the system to become extremely slow.
