Bug ID: 430127
Summary: KStars Crash When Imaging with ASI6200MC-Pro
Product: kstars
Version: 3.5.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: general
Assignee: mutla...@ikarustech.com
Reporter: mountainai...@outlook.com
Target Milestone: ---
SUMMARY
KStars running on RPi4 (Stellarmate) seems to crash 3-4 images into an imaging
sequence with this large-format camera. A single image shows memory use climb
from 33 to 66%, but as KStars continues to image, this climbs to 100%. Then
CPU pegs at 100% as well. At this point either KStars crashes, or it does not
crash and the entire machine locks up and must be power-cycled.
STEPS TO REPRODUCE
1. Connect ASI6200MC-P. Monitor CPU/memory via VNC or Stellarmate app.
2. Configure capture module to take 100 frames binned 1x1.
3. 3-4 frames in, KStars will fail.
OBSERVED RESULT
KStars crashes or machine hangs.
EXPECTED RESULT
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: Stellarmate 1.5.5
(available in About System)
KDE Plasma Version:
KDE Frameworks Version:
Qt Version:
ADDITIONAL INFORMATION
I wonder if RPi4 is just not powerful enough (especially the 4GB memory limit)
for these huge images. However, is there a way to turn off the FITS viewer to
avoid that memory overhead? Hopefully there's no memory leak there, but I did
notice that after each frame, the %memory increased higher than the previous
frame.
