Ekos Polar Alignment Tool Crashing was created by MrLunas

Hi guys,

last night I was trying to use the Ekos Polar Alignment Assistant Tool. After successfully solving three images the tool crashes (after "WCS data processing is complete.") and I have to restart kstars and ekos. I tried several different settings like the resolution of my camera or the slewing direction.

Equipment:
Mount: IOptron Cem25p (IOptron Cem25 driver)
Scope: TS Optics 71SDQ
Camera: Sony SLT-A58 (GPhoto CCD driver)
Control: Raspberry Pi 3B+ with Ubuntu Mate (headless)

I hope you can help me with this and for more information I attached the log file. (Some parts of the file are in german, because I am from germany)

What KStars version? In the log everything appears to be OK. Maybe running KStars via gdb with the backtrace would get better results.

Thank you Jasem for your quick reply. I am using KStars version 3.1.1 and updated it to version 3.2.0 today. When I try the process with the CCD Simulator, everything works. I don't know why it's not working with my DSLR, because everything else works perfectly.

I attached the startup log for information.

Can you run KStars via gdb?

gdb -ex run --args kstars

If it crashes, type in bt to get the backtrace and then paste it here.

I can run KStars via gdb. For testing it with my camera I need a clear night to make the three pictures. Then I can post the backtrace.

Hi Mrlunas, what computer are you using?

I had similar issues with my Raspberry Pi3. Have you tried down sample in the Solver Options?

My fix was a computer with a bit more RAM.

I was thinking about lack of RAM as a possible explanation for this issue as well. Mrlunas, you may want to look into setting up zram on the RPi to see if that resolves the issue.

Hi Petar and Wouter,
thank you for your advices. I will try them next night. I use a Raspberry Pi 3B+ and control it via RealVNC. Maybe zram will help my pi :)

Hi Wouter and Mrlunas, yes i did not actually try setting up a swap partition on my old RPi3, but this maybe worth a try.

Hi Petarm,

It is my understanding that it is not recommended to use a swap partition on RPi because of the heavy I/O involved which wears down the SD card rapidly. That's why zram is recommended.

Back after a clear night kstars crashed again. This time I used gdb and copied the backtrace. I hope it helps to solve the problem.
