Error: out of memory (macOS vs Windows 10)

[tycruickshank]

Hi, I'm very new to PixInsight and have really been enjoying the process of learning how to use it. I've been following the pre processing tutorials from Light Vortex Astronomy https://www.lightvortexastronomy.com/tutorial-pre-processing-calibrating-and-stacking-images-in-pixinsight.html which have been very useful.

I'm trying to integrate 256 bias frames that I've taken with my Nikon D7200. Strangely I can do this just fine with my 2016 MacBook Pro 15" with 16gb of memory, but I get an out of memory error when doing the exact same thing with the same settings on my Dell Precision 5530 with 32gb of memory. I would've thought the machine with twice the ram would not have a problem.

I'm not sure if this is perhaps a configuration problem on the OS side of things. I've been mostly a Mac user for 15 years now and have used Windows here and there so perhaps I need to tweak something? I just got the Dell about a week and a half ago so it's a brand new machine. I did not do a complete fresh install of Windows 10 on this computer when I got it because it seemed like there wasn't much bloatware since it's in the workstation class (Precision). Is there something I need to adjust in either PixInsight or Windows to get this to work?

I noticed that after I ran the imageintegration process the first time with this number of bias frames the pagefile.sys seemed to become quite large (58gb as of writing this). Does Windows 10 dynamically manage this swap file depending on whether or not it's getting used?

also an osx user so take this with a grain of salt - i think windows does manage the pagefile but there might be some hard upper limit when in auto mode? or maybe just tied to disk space on C?

The out of memory can also be low hard drive space since PI tmp files and Windows pagefile are both stored on your hard drive.

Rob, thanks for the link. I'll give that a shot if freeing up some hard drive space doesn't seem to help me out.

Mike, thanks for the tip regarding that. I have 186gb of free space out of 512gb. Does that sound like it may not be enough to process ~250 raw files of ~30mb each?

I'm discovering processing astro images sure eats up hard drive space like crazy. Definitely going to need additional external hard drive space.
