Whether or not it sounds right, it was indeed the case for us
on Onyx RE^2 with Performer 2.0.4 until we installed patchSG0002739.
Occasionally, wayward graphics processes would hang, preventing
use of the graphics console and inhibiting the launch of any
more processes accessing the display.
These processes were unkillable by root (well, the APP process
could be killed, and what appeared to be the DRAW process would
become a zombie, and never be cleared up by init the way the man
page says should happen periodically). Stopgfx/startgfx was
ineffective. The only workaround to regain access to graphics
was to reboot the machine.
Obviously, user processes should not have this disruptive
power on a multi-user machine. However, it was most definitely
the case.

Jean Daigle.
