Vernon is correct. The 3.2 bug that would hang a MP machine (when accessing
ttyf* or ttym*) was fixed in 3.2.1.  Any release greater than that will 
also have the fix (3.2.2, 3.2.3).  If you have a support contract and do
not have on of these loaded on your machine, or available to you, contact 
the SGI Geometry Hotline.
