I'm sorry to bother you once more with this query but I must have explained
my problem in my previous query very badly.

I have some problems with our 4D/70GTB. Quite frequently the screen goes black
in the middle of a graphics session. No this has nothing to do with the
screen blanks after some time intervals. There is now way I know of to get the 
display alive again. (I have not tried a hammer). (We had problems with one
of the graphics boards which was replaced some weeks ago.) One of the things 
I tried was to kill grcond and restart the graphics. Some times this works. 
The problem is that it is usually impossible to kill the old grcond. Usually I 
just boot the system. This is very annoying because we are running quite long 
jobs in the background. The next thing I did was to look into the SYSLOG file 
and found the following things:


......

Oct  3 12:56:58 geeni grcond[9658]: Child process /bin/news_server terminated with status 0

Oct  6 13:02:26 geeni grcond[3548]: Child process /bin/news_server terminated with status 6

Oct  6 11:07:42 geeni grcond[3396]: Child process /bin/wsh terminated with status 0
Oct  6 11:07:44 geeni grcond[3396]: CIO: NeWS: segmentation violation signal received
Oct  6 11:07:44 geeni grcond[3396]: Child process /bin/news_server terminated with status 6


What's the problem when /bin/wsh exits with status 9 and /bin/news_server exits
with status 6 and what might be the problem to the bus error and segment 
violation? I phoned the local SGI service and a chap had a look at the
system but he did not find anything wrong with it. And the screen still goes
black. Is there any suggestions?

Many thanks,
