Hi everyone

Selecting around 15 stars from the apo mask:

Hi,

I've tried for a while, but have been unable to replicate this on substantially similar hardware and distro.
That said, I'm inclined to think the issue is likely the very low amount of virtual memory at your disposal; 8GB is not a whole lot - a better amount would be 2x to 3x the physical memory (16GB or 24GB in your case) at a minimum.
Have you tried installing swapspace (which essentially allocates as much as your system needs)?

Thanks Ivo.
I've set 24Gb swap (using dd and swapon) and have been unable to reproduce.
Looking good.

For whatever its worth, I've had great success using SVDecon with GPU-enabled ST and 32GB of system memory...except...on a couple of occasions, SVDecon crashed when I selected a star that straddles the outer edge of the window border; don't do it anymore and no issues.

Great to hear! :thumbsup:

It's looking like the next Release Candidate might be final release version of 1.8.

This should definitely not happen any more on the latest RC. If you still see this, do let me know.

I'll let you know but have not seen it happen since running latest rev; things look stable and solid.
