Program keeps getting killed #30

Closed raduprv closed 2 years ago

raduprv commented 2 years ago

Hello, I am trying to use focus-stack on a 8GB RAM Mint Linux machine, and the program keeps getting killed. No information on why it gets killed. If I use --full-resolution-align then it is guaranteed to get killed, even though I am using 16MB images. Setting the batch size to 4 helps (won't get killed if not using --full-resolution-align). Any idea what could be wrong?

Thanks, Radu

Sounds like you are running out of RAM. With the default settings, about 100 MB of RAM is needed per every megapixel of input image resolution. Reducing --threads and --batchsize reduces memory usage. And other applications take RAM too, so you can check how much you have free to start with by running free -h.

I have about 6.5gb of free RAM. Would it be possible to autodetect the free ram and auto adjust the batch size and everything else to match it?
