Was this software released without being tested?

I'm on the verge of going back to SGP.

Hi!

well, all software have issues, for a great variety of reasons. Do you have any particular that would cause you to abandon this project?

My crashes were identified and solved by Jasem right now. A level of testing and fixing that beats anything I ever experienced in commercial software...

So as for the thread topic: at least one cause for crashes seems to be solved, as we speak.

Hi,

I have the same experience - Kstars suddenly crashes/disappears.
Last time it happened it was right after a meridian flip, in iteration #2 of the solver (please see attached log).
It seems it happened right after the image taken by the solver was downloaded.

I also often get this behaviour after I have captured my flat frames and start taking the first light frame.
To reduce the risk of this to happen, I now have a routine to always restart the Stellarmate between the flats and the lights.
Not very convenient, but I rather do this than having a crash during the lights session...
So it seems to have something to do with the image capture in my case.

Any ideas/advice on what to do?

Cheers, Åke

Hi!

I have no clue to what happened there, but as I understand it, you did not run Kstars from the Ekos Debugger?

I think that is a very good idea to get data on the crashes. Logging data is in the Debugger window, and you choose a directory to save it in as well (do that before you start Kstars with it).

Hi Magnus,

Thanks for responding so quickly.
Not sure what you mean by "run Kstars from the Ekos Debugger".
I did enable debug logging when starting Ekos, but that is after I started Kstars. I don't know how to start Ekos in any other way, please advice me. Currently, I start Ekos from the Kstars menu: "Toggle Ekos".

Also, not sure if I should enable all logging (since it says "Only enable the necessary logs to help in diagnosing specific problems").
I think what I enabled was:
- Ekos: INDI,Capture,Alignment & Mount
- Drivers: Mount & CCD

ekosdebugger is tool that you use to launch KStars so that in case it crashes, it can generate useful logs for developers. You can install it on Linux:
sudo apt-get -y install ekos-debugger

GM everyone,

I'm sharing my experience and what I believe went wrong (and fixed) for me. I was using a USB extension cable to increase the length of the RPi power cord. When I tested this on my RPi test unit, the insufficient power warning was always popping up. I suspected that I'm using the old power supply for RPi 3, but it was the extension cable. The volt was correct but the Amp dropped below 3A. I removed it yesterday and I was able to get a continuous session for more than 6 hours without interruption. I used the ekos debugger, but there were no interruptions to report. There were other problems, but it was my mistake in ekos configuration.

Thank for the reply.
So I installed the debugger, but how do I launch KStars with it? Sorry for my ignorance.

If you launch it, make sure you're in the KStars tab, then click the Play button.

OK, but how do I start the debugger? I can't find it anywhere...
EDIT: I see it now, I have to start it from the command prompt!

It seems to crash randomly. I'm playing around a bit to try to provoke it and this time it crashed when stopping Ekos by clicking the "Stop"

The debug log is attached. It doesn't show much I believe, but the following showed up in the EkosDebugger window:

Don't know if this helps, but it doesn't seem all random.
I've got a feeling that the crashes normally happens where there is image capture activity of some kind, either when changing between flat frames to light frames or when there is an interruption by e.g. a meridian flip and the solver needs to capture some images.
Also in the output I provided in the previous post there are statements like "ISD::CCD::loadImageInView".
Could it be something in this area?
