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.

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.
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.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 [2025-04-13 16:24:12.508497] [0x00007efc1da0e540] [trace] Initializing StaticPrintConfigs add font of HarmonyOS_Sans_SC_Bold returns 1 add font of HarmonyOS_Sans_SC_Regular returns 1 add font of NanumGothic-Regular returns 1 add font of NanumGothic-Bold returns 1 loading network module at /home/gene/.config/OrcaSlicer/plugins/libbambu_networking.so after dlopen, network_module is 0x560ef8e3ede0 1. lo : 127.0.0.1 2. eno1 : 192.168.71.3 3. docker0: 172.17.0.1 This is probably 20k lines into the strace.comb output by running "OrcaSlicer &>strace.comb": ioctl(65, SIOCGIFCONF, {ifc_len=2048 => 120 /* 3 * sizeof(struct ifreq) */, ifc_buf=[{ifr_name="lo", ifr_addr={sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("127.0.0.1")}}, {ifr_name="eno1", 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 ioctl(65, SIOCGIFNETMASK, {ifr_name="eno1", ifr_netmask={sa_family=AF_INET, 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, whichappears 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.
Thank you Andy. That, at 90 yo, is beginning to be a problem, my diabetes is getting harder to control.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 (amacater@debian.org)Stay well - all the best,
