SUMMARY I have been trying to use KStars for a few weeks now. Crashes are common, generally happening several times per night. Last night I swapped out my ASI294MC-PRO with an ASI1600MM-Pro and spent 5 hours in the cold with not one good set of images because I experienced 20+ crashes. Unfortunately I did not filter my actions down to the minimum set to trigger a crash, but I will attempt to do so. Here's my workflow for the evening: STEPS TO REPRODUCE 1. Launch KStars and Ekos. 2. Start profile (Celestron CGX, ZWO Main/Guide Cam, UltimatePowerBox (I have v2, no driver yet), ZWI EFW, SkySafari. 3. Plate-solve. Works fine. 4. Auto-focus. Works fine. 5. Auto-guiding. Works fine. 6. Start a sequence of 5 x 30-second Luminance photos. OBSERVED RESULT The first 2-3 photos work, then KStars crashes. Previously I didn't have a problem with sequences; the only change was the ASI1600MM-Pro, but they use the same driver (I suspect). What is strange is that I can capture single images and loop indefinitely without problems, but when running a sequence it fails. I somehow lost the crash report, but I will try to capture another one tonight. EXPECTED RESULT Running imaging sequences all night long without crashing. SOFTWARE/OS VERSIONS Windows: macOS: Catalina, all latest updates Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Update: Connecting to Ekos remotely from another Mac running Ekos also results in a crash during the sequence run. Connecting to a Raspberry Pi 4 remotely running StellarMate OS and KStars 3.3.9 also results in a crash while trying to run a sequence. Running KStars/Ekos on the rpi4 also results in a crash during the sequence (I only tested it once; I made it 6 photos into 140). There is clearly something wrong with the sequence action. Perhaps it has something to do with then combination of hardware I'm using -- but it is all very common hardware. I was still unable to capture a crash dump; for whatever reason it only generates one intermittently.
Here's a crash report from my oldest MacBook Pro (2013): Process: kstars [649] Path: /Applications/KStars.app/Contents/MacOS/kstars Identifier: ???

Created attachment 125384 [details] Crash report Crash report.
Can I ask you about the issue you're having? As I understand it, you're running 3.3.9 on a Mac/Catalina, with all your devices also connected to the Mac. Then, I see you say you tried a Raspberry Pi remotely. I assume that means the devices connected to the RPi via an IndiServer, and you ran EKOS on the Mac. Can you try running everything on the RPi4? Does that crash too? If you do try this again, can you please run the latest nightly with your ASI1600MM-Pro? I'd love to be able to reproduce this (and I have that camera so I could run a very similar configuration with the RPi4 and ASI1600mm). Please log with debug on for everything and send the log file. Thanks!
I just noticed that Jasem and I fixed an issue recently that would be consistent with your stack trace. If you can retry with the latest code, it may solve your issue. That said, there may not yet be a "latest code" for the mac yet--as I understand, rlancaste is working on that. However, the nightly code for the RPi4 should be available. If/when you can test the latest code (Mac or RPi4), please let us know if this issue is resolved.

Thanks! I did try running everything on the PI4 once (I was VNCing into it), and it did crash during the same workflow -- but I had only tried it once. I will try the latest build and will report back with a proper crash log. Thank you!
INTERESTING OBSERVATIONS: #1: While working on some configuration issues with the scope set up in my house, I took 1000 1-second photos without a crash. I was not guiding since I was in the house, but when I attempted the same scenario outside later that night WITH guiding, it crashed repeatedly. In some workflows I couldn't get more than 1 or 2 shots. #2: This led me to some experimentation. Working on the assumption that guiding seems to cause this, I discovered that duration of the main cam dramatically affects the observed instability. With the guide cam taking sub-framed/ROI'd guiding images every second (ASI174MM), and the main cam taking full 1-seocnd photos, Ekos seems to crash within a handful of main cam photos. But if I increase that duration, crashes dramatically reduce. I've been taking 300-second photos for over an hour now with no crashes. So... very short camera exposures and/or collisions between processing imagery from two higher-frequency cameras seems to be the cause.
I had to give up on the RPi4 beta of StellarMate OS because of various connectivity and stability issues, even with an ethernet cable running to the backyard. However, when I switched to RPi3 I was pleasantly surprised. In contrast, it is a joy to use. I still run into occasional problems, but its WiFi is reasonably strong even through the closed patio door. One BIG issue is that when I run the software update utility on the desktop via VNC, it seems to make everything worse (both RPi3 and 4). For that reason I have not updated to the latest KStars. On RPi3 it actually breaks the package update system, and even after repairing it via shell I was unable to get it running reliably again. This happened multiple times, requiring a re-flash. However, I see that I can update KStars alone via the StellarMate app on iOS, so I'll try that with a duplicate SD card. I still have not tried running an imaging session on the RPi3 itself, per your request. I will try that, with short exposures, before and after the update and will report back when I can.
Please test on 3.4.3 and report back
Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone!
More recent builds of KStars have been crashing less frequently, and 3.4.3 seems quite a bit more stable. I haven't experienced this crash during an imaging sequence for many months. Closing ticket. Hy, I apologize for not seeing your earlier comments -- had I been paying more attention, I would have responded. Thank you both!
