(Actually, I mean the logs that ISIS writes out when you use cmd snap:
after doing cmd snap, you find files called xxxx.log in the directory where
your application was running.  These are the ones that might have been
helpful).

>(more stuff, deleted)

Looks like an old problem.  Switching to a more recent SUN OS release
or ISIS release or both would certainly fix it.  We didn't introduce a
work-around on these TCP channels not breaking until we had actually
seen the problem, and you are apparently still on the ISIS and SUN OS
releases which predated us introducing the fix.

As a work-around, I think that an explicit call to isis_probe(60,30)
should do the trick.  But, test this before running your demo!

Another data point. I just got around the problem with restarting ISIS
by restarting ISIS at another site first, e.g. I did "isis -Z" on the
sun4 that was giving me trouble, which shut down all sites, then went
over to another site and fired up ISIS, which went fine, then came back
to the trouble site and restarted ISIS and it fired up. This was the
message I was getting when I tried to re-start ISIS in the trouble site
after I zapped:
---

This went away when I applied the procedure described above. Immediately
after restart, I can also run the program that was giving me troubles,
from which I posted code fragments. It will be interesting to see how
many times I can fire it up before I can't anymore... is this a problem
with a process dying in an "uncooperative" way, e.g. dumping core (not
calling exit(2))?

Anyone know what the hell is happening? I sure don't.

  (description of a join problem)

I can see from your log that everything is piling up waiting for
replies from one or two of your clients (e.g.: sent to xxxx, status W
means "waiting for a reply from xxxx").  But, lacking logs from
xxxx I don't know why.

Some random ideas:  if TCP channel breakage is not always working
right on your systems (and this is a common thing we see on SUN
systems, for example), then if isis_probe isn't set you might have
Isis fail to notice that xxxx is dead and so hang.  But, I bet that
this is not the problem.  V2.2.7 and V3.0.7, at least, would not have
such a problem.

Some evidence that your TCP is having trouble is the failure to restart
after shutting down: seems that UNIX is not deallocating the TCP
data structure in the kernel and hence Isis can't reopen it.

SUN has problems in this part of TCP in one of their releases a while
back.  If you are on ISIS V2.2.5 on a SUN 4.1.1c platform, for example,
this could explain it.  But, later releases of SUN OS and also of ISIS
(either of them) would probably not have this problem.

Another idea: if you try and join multiple groups, say that p joins
A and then B and q joins B and then A.  If they don't call isis_start_done
FIRST, then they can deadlock because p needs to help q on its join
and vice versa.  Would only see this for "concurrent" join situations.
This could explain why adding some extra groups caused the problem --maybe
you did so in a way that introduced a cyclic join pattern?

Did you find client-created xxxx.log files after your snapshot?  When
you see protos log files that show people waiting for certain programs
to take an action, the next step is to have a close look at the state
of those programs...

Apologies for adding to the network noise, but this seemed like the logical
place to inquire.  

Is there a news group dedicated to distributed computing in general, rather
than just isis?  From just looking at group names, it doesn't appear as
though that area has a dedicated group.  Is there any interest in one?

I recently heard about an effort at Univ. of Illinois (NCSA) in the area of
distributed computing called Blanca.  Is this fact, fiction or just
misunderstanding?  Can anyone give me a pointer to follow?

Because chances are that the higher clock speeds don't conform to the more 
rigid RF specifications used in Europe and Japan.  The FCC standards tend
to be slightly more lenient than some of those others in certain areas.  But 
I would be interested to see a GS tested for class B with a Zip running at 
about 15 MHz or so..  The fact that the low power Zips and RamFASTs flake
out sometimes could very well be due to them failing class A certification 
which only specifies susceptability requirements.  Since they're only selling
components and not the final computer, I'm not sure how the FCC regs work on
that point.  I do know that any computer system used in the home that fails
class B can get you fined $1000/day of use (after detection) and/or system
confiscation.  And companies that MAKE computers that fail class B can get 
entire shipments confiscated!

Great.  I'm happy for you.  I agree it's a greater waste of bandwidth
talking about it here.  Here are suggestions Jerry Penner and I have been

1.  If he doesn't have time to edit it, I'll edit it for him.  
2.  Shrinking.  If the size of a shrinkit archive is around the same size
as an average edited issue, then fine.  Post it as is to the binaries.

See, I'm not rotten, and I'm not saying this because I'm a sysop on a
competing system.  I'm just concerned about MY users on my system.  NEWS
on the systems I control isn't a high priority item -- when I run out of
disk space on a filesystem, something has to give and in our case here,
it's news.

    Underlining shouldn't affect letter spacing, but bold and italic might
cause some unwanted side effects.  None of the WP/DTP software I use on the
GS handles "fractional spacing".  You need that when you edit a document on
a low-resolution device and transfer it to a high-resolution device for
output.  On a StyleWriter, one screen pixel (typically the distance between
letters) translates to 5 printer pixels.  Therefore, you can only have some
multiple of 5 pixels between printed letters.  What happens if the optimum
spacing is, say, 3 pixels?  It gets rounded off to 5 pixels.  That's one
reason why spacing sometimes looks erratic.  Bold and italic styles affect
character widths, and the effect is amplified on the printer.  I find that
outline fonts don't have this problem, but *make sure* you are using "true"
bold/italic/bold-italic outlines, not the QuickDraw II synthesized ones.

Or there are a lot of host machines that the same group of people have access
to.  Like the uiuc student system, where an engineering student can have access
to (depending on how you count it) over 300 machines.  And over a hundred can
be on the same account.  Also, any student here automatically has access to 2
machines.  Possibly more.  Just a thought.

The last time I ran into the guys from ThunderWare, I asked them the very

I think it'll be expensive though. I've seen the Mac LightningScan software,

I don't know about AWGS 1.0, but AWGS 1.1 and Teach can use the extra
characters. In a control panel, I think General, you have to set Keyboard
Translation. I think the options are none and normal. You want normal. Try
pressing some keys with the option key down. Shift-option also gets you a few
characters. You should upgrade AWGS to 1.1. Most programs should work with the
extra characters w/o any changes.

I tried loading in a text file with low and high bit
alphabets.  (I wrote an AppleSoft program to create this file by 
writing asc codes to a TXT file.)  It didn't work; both
sets appear to be low bit.

Any suggestions?

Prosel-16 can launch documents. I don't know of any 8-bit launchers that do,
but I don't know anything about the available 8-bit launchers.
