Greetings from a cold and wet Finland. Apart from the weather I have in
mind a problem with our 4D/70GTB. Quite frequently the screen goes black
in the middle of a graphics session. I have tried to kill the grcond from
an other terminal but without success. 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 following 
things:


......
Oct  3 12:56:53 geeni grcond[9658]: Child process /bin/wsh terminated with status 9
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]: CIO: NeWS: bus error signal received
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,
