SUBJECT: Question: Problem with OS/2 Client

Last Thursday I posted a note to the OS/2 ISP Mailing List about our
effort since there was a posting for the Sollen group. I have received
several reports of problems. Since I am not sure who to let know I am
posting this here. At the bottom of this note I am including all of the
posts. Some of the people are getting trap errors. Any help for them
would be appricated.

TIA

For those in North America also look at:

OS/2 is in tenth place and could move up to 6th with a little help. I
have had 3 OS/2 machines on it 7/24 for the last couple of months. I
can't tell that it is running, it has so little impact. Take a look at
both groups.

This is not directly on topic.

The subject is more like OS/2 Advocacy but I thought that OS/2
ISPs, like myself, would be interested in participating since: 1. They
are probably OS/2 fans 2. They have internet access 3. They have
machines which are on all the time and probably have a few spare CPU
cycles.

Some RSA encryption people have a contest to break a 56 bit code.
One of the groups involved is using a brute force technique. Go to
http://www.des.sollentuna.se/ to learn more about it. My interest in
helping is based on the fact that some of the STATS they publish rank
the platforms used in breaking the key. The OS/2 client became
available this month, well after the others, and has already made it to
9th place. It has the potential to get to 5th place at the current
rate. It is also interesting to note that in the benchmarks the OS/2
client does slightly better that the Linux and Win32 clients on
equivalent hardware.

The client can be configured to run at any priority. The most
useful being idle priority which has little impact on the system.

Hint: they use frames. If you are like me and have problems
finding the links, then look in the frame on the left hand side. Stats,
Download, etc.

Incidentally, the tilde was mistakenly omitted in the above URL; it
should be:

I tried the OS/2 client on an Intel 486 with 32 RAM running OS/2 v3 (no
fixpacks) and after the first keyblock, the machine trapped. Anyone
else? Or better, any solutions?

Since this is really getting off the list-topic, feel free to e-mail

background, and then a few minutes later, my system would lock harder
than ever. Stop running it, and the locks go away.

Well, I've been runnning deschal4 on a system at home for a couple weeks
without any lockups. System is Warp 3 Connect, AMD 486DX2-80, 32MB.
Running TCP/IP, Peer, etc. I have seen deschal4 just stop processing a
couple times, but I killed it and restarted it, and it was fine. Other
than that, it just sits there and chugs away pretty much unnoticed:
Here's some stats:

I too have had problems with DesChal, but not within minutes.

1. No problems on Warp Connect (DesChal4 AMD486-120 32 meg) 2. With
Merlin and peer, attempting heavy access to a shared drive crashes the
client machine, and renders
peer useless on the server (net stop peer, net start peer fixes it)
. (DesChal4 AMD486-80 16 meg) 3. With Merlin and Stack40, hourly
crashes. (DesChal4 AMD486-120 32 meg) 4. With Merlin and Stack40, daily
crashes (DesChal4 P100, 16 meg) 5. A co-worker w/ Merlin w/o Stack40
has no problems (DesChal5 Cyrix 166+ 32 meg )

(yes, I need more ram)

Crashes included Traps 7, c, d, e, and f. Often in in IFNET. When I
first started running DesChal, I had just installed stack40, InetMail,
upgraded PowerWeb, upgraded PMMail, and DualStor (I will never spend an
afternoon "catching up" again ) so I wasn't sure of the culprit.
Logically, DesChal seemed the least likely. Since then, I backed out
everything one at a time (DesChal last), and reinstalled everything one
at a time. Without DesChal, I haven't rebooted any machine in a month
now.

Whether or not the above scenarios are relevent, I don't know. ie, I am
not suggesting that stack40 is a probem, I'm just telling you my results
on my configuration. I'm not much interested in experimenting anymore.
Maybe someone can find another common denominator here.

Could it be DesChal3 and DesChal5 are fine, but DesChal4 is buggy?
Seems unlikely, but I don't know what he does to optimize for a 386,
486, or Pentium class machines. Another long shot suggested to me is
that since I seldom sustain 100% cpu usage without DesChal, it may be a
heat problem. All my systems have heat sink compound, heat sinks, and
all the fans are spinning.
