SUMMARY When capturing images during the polar alignment routine, the Mac version of KStars connected to StellarMate sees long delays and a spinning beackball cursor. This can often delay an image 30 seconds, making most short-duration operations in KStars almost unbearably long. This may happen in other modules that use the camera, but I tend to not get past alignment when it happens. Quitting and restarting KStars and StellarMate has no effect, nor does rebooting the Mac. Note: Could this be related to the Wi-Fi network at my dark sky site not having an Internet connection? Maybe that’s why I never seem to experience this at home. This did happen to me once before, but it somehow went away on its own. Now it’s back. Unfortunately I enabled logging but missed writing it to a file. I will try to capture a log later tonight. STEPS TO REPRODUCE 1. Launch KStars on Mac 2. Start equipment profile that points to StellarMate 3. Enter alignment module 4. Begin polar alignment OBSERVED RESULT There is a long delay and a “spinning beachball of death” before each captured frame. EXPECTED RESULT No delay. SOFTWARE/OS VERSIONS Windows: macOS: 10.15.5 Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
I was able to capture logs of the spinning beachball capture problem, but I couldn't send them that night because I was in the middle of the desert with no Internet access. Today I fired up KStars, opened the logs directory... and the only logs I had were from today. Does KStarts automatically delete logs for previous days? If so, can this be configurable with a 10-day default?
For what it's worth, the last time I was at the same dark-sky site with the same equipment and the same network gear, this beachball behavior on each image capture did not occur. There were no other changes in running software, etc. Unfortunately these intermittent issues are the worst to track down, but if it happens again I will capture the log.
Created attachment 130071 [details] Spinning beachball log Spinnig beachball delay between exposures on Mac.
Hi Jasem, I was able to reproduce the spinning beachball problem (log attached), but I'm unsure why this happens some nights and not others. I can see a roughly ~30s delay between exposures in the log. This is perhaps not a great example because it happened during the polar alignment wizard, but I'm pretty sure it was not a plate-solving delay. Thanks for looking into it!
Happens also in 3.5.0?

I am not sure if this still occurs, as I stopped using remote connections from one Kstars/Ekos to another. However, due to another issue with memory use on RPi-4 and full-frame cameras, I will need to test remote connections the next time I am at my dark-sky site. I will report back at that time.
