I have had the following problem for a few months:
We have here sun 3/60s running sunOS 4.0.3 running dataless. Their
/usr partition is exported from a sun 4/280 running sunOS 4.0.3. Lately we
have found that sometimes when we run sunview not all the command
tools and the console window show up. Using top we find that the
tools are running and are usually taking up an exorbitant amount of
the cpu. A lot of the people have complained that this happens after
the previous user has used X windows. Initially I thought this could
not be possible but now I've found some things that may indicate the
opposite:
When users exit from X, the terminals they were using (ie
ttyp1 ttyp2 etc) when they were running X still show up when they type
finger.
So it looks like X exits but doesn't clean up after itself properly.
Let's take the following scenario:
user-a runs X and starts up several x-terms and then exits
(usually by selecting Exit from twm as this is the last process
running in .xinitrc for most of them) and logs out. user-b logs in
and tries to start sunview. All his mailtools, clocks, textedits and
dvipage previewers come up OK but no command tools or shell tools. He
exits and types finger and sees something like the following:
Login Name TTY Idle When Where
cbridge Chris Bridge co Thu 18:22
mferrare Mark Ferraretto p1 1d Wed 14:45 unix:0.0
mferrare Mark Ferraretto p2 1d Wed 14:50 unix:0.0
mferrare Mark Ferraretto p3 1d Wed 16:41 unix:0.0
and so on.
Let us assume that ttyp0-6 are taken by mferrare.
cbridge starts up sunview again and this time asks for command tools until they
appear. He types:
tty
and gets:
ttyp7
This implies to me that command tools (and shelltools) aren't starting because
the slots ttyp0-7 are taken by mferrare. This means that X isn't exiting
properly. Incidentally, when mferrare started sunview up after having run X
there was no problem. This seems to imply an ownership problem with the ttyp*
Is this the case? What can I do to fix it?
Many thanks. I'll summarise if interest warrants
