Hi Gene,
I'm probably going to regret this - let's see if I can help you
fault-find :)
Questions:
1. Which version of Debian is this?
Give us the output of /etc/os-release and of uname -a on this machine,
please.
<snip>
PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"
Linux coyote 6.1.0-33-rt-amd64 #1 SMP PREEMPT_RT Debian 6.1.133-1
(2025-04-10) x86_64 GNU/Linux
So, Debian 12.10 and right up to date with the latest kernel, not
self-compiled.
correct.
2. Do you actually *have* orcaslicer 2.3.0 installed - or is it left
over from some previous attempt at installing something you later
removed?
OK - you do have it installed as you mention below.
yes
All of these AppImages run just fine, once the freeze has timed out.
Orcaslicer, PrusaSlicer, OpenSCAD, everything runs normally except for dim
to invisible for /some/ of the teeny little 8x8 menu icons.
3. What does the command
ip a
gene@coyote:~$ ip a

show on your system?
At last, some output :) OK - docker0 interface is not up. It looks as if
docker0 would be on 172.* network - again, non-routable outside the machine
if I'm right. Bring up docker0 ?
I've never before had any experience with docker. I am behind a new
router with brainslayers dd-wrt a/o about 6 weeks ago. I don't worry
about security too much when that guard dog is controlling outside access.
So the next question is How do I get docker running? Data point: There
are quite a few "polls" in the strace output for fd's at lower numbers,
giving me a feeling that docker has a limit to the number of times/paths
it can service. But since I've no experience with docker, what do I do
to fix it? And is it a system problem, or AppImage problem? AIUI
docker is a vPN workalike. Please correct me.
4. Do you have docker (or podman or buldah) on your system?
Ah, you obviously do have docker installed / had it installed :)
Do ack synaptic.
5. Can you *show* us the output from strace, please - capture a few
lines.
the possibly interesting part involves docker:
here is all of >strace.stderr

2. eno1 : 192.168.71.3

This is probably 20k lines into the strace.comb output by running
"OrcaSlicer &>strace.comb":

ifr_addr={sa_family=AF_INET, sin_port=htons(0),
sin_addr=inet_addr("192.168.71.3")}}, {ifr_name="docker0",
ifr_addr={sa_family=AF_INET, sin_port=htons(0),
sin_addr=inet_addr("172.17.0.1")}}]}) = 0
ioctl(65, SIOCGIFNETMASK, {ifr_name="lo", ifr_netmask={sa_family=AF_INET,
sin_port=htons(0), sin_addr=inet_addr("255.0.0.0")}}) = 0

sin_port=htons(0), sin_addr=inet_addr("255.255.255.0")}})
I should advise since its Sunday I just updated with synaptic to a new
kernel and rebooted then installed a couple more pieces of docker so the
error output isn't exactly the same.
OK - that's understood.
None of us are mind readers - none of us are sat looking over your
shoulder. Without something to go on, every message from you about
problems involves significant guesswork. Share information, please,
about what you are *actually* seeing on screen in front of you and
make it easier for the rest of us. The Sherlock Holmes approach is
fun the first few times, but you're making it hard for us to eliminate
the impossible and work on the problems in hand.
[If this helps, imagine this was a problem at a TV station that someone
you didn't know well was reporting to you over the phone. You'd be asking
questions and noting down the responses to be able to narrow down on what
the issue was. You're expecting all of us to *know* the answers from zero
information given: it's frustrating as anything.]
Chuckle, BTDT for nearly half a century Andy, I'm quite used to using
somebody else's hands over the phone. Probably, as you have seen, not so
good letting somebody else run my hands.
This is a heck of a lot better though, Gene, because at least you're
showing us relevant output.
Using strace, the freeze corresponds to a poll command for fd33, which
appears to be a docker function. In this case the test file is an AppImage,
orcaslicer-2.3.0, but any AppImage will work for this. I have quite a few,
as its the only way to get the latest and greatest given debians penchant
for dragging feet about projects that s/b debs but for some reason don't fit
the debian POV.
That 2.3.0 version is the latest, not a leftover. PrusaSlicer switched from
AppImage to a snap for the newest version and the install and is nearly 50k
files.
So PrusaSlicer is an older version and has a couple warts but my printer
needs heavy mods to the print startup gcode I've not yet incorporated
into OrcaSlicer. I have made a motorized nozzle cleaner that needs
additional gcode to enable it. No other printer on the planet can do
that. It is a cobble job of printed parts and 2 more motors, but it
Just Works.
This freeze I'm looking for started just as I figured out how to
stuff a pan of hot mashed potatoes in orca's mouth and still reboot. Orca
had only one volume, wide open and its announcing every key I pressed was
close to me using my venison collector to put it out of its misery. Thanks
Andy.
But while there is a call to docker on an ipv4 address starting with 172 in
the trace output, I don't recall ever setting up docker on this system. So
who can help me check to see if its missing and this freeze is the timeout
while its waiting for docker to reply to the poll?
Cheers, Gene Heskett, CET.
Thanks, all the best, as ever,
Andy

Stay well - all the best,
Thank you Andy. That, at 90 yo, is beginning to be a problem, my
diabetes is getting harder to control.
