Not really a SuSE or a scilab user, I'm afraid. Changing the
init level to 3 probably on worker nodes probably turned off a
local X server, of course, but it seems pretty unlikely it
would have been usable by batch processes unless the X server
had also been configured to allow it (out of box on modern linux
distros, the [kxg]dm-managed X11 server typically wouldn't allow
unauthorised connections from clients, to the best of my knowledge),
and even then the batch job would have to happen to have a
correct DISPLAY env var, assuming scilab needs a valid display.
Was scilab itself upgraded? (I have no idea if it's "in SuSE" -
all I know is that it's non-free): could just be a bug in scilab,
failingto do whatever it's supposed to do when given -nwni, assuming
what it's supposed to do when given -nwni includes not even
trying to use any X display.
