Hi,

I don’t seem to find a credible solution to this problem. Some mention of bad data causing this but I am running the job with a tested dataset and it still fails.

Running WebODM (WebODM 1.9.6) in Windows 10, using Docker Toolbox.
Allocated 4 cores to the VM and 12 Gb RAM
Browser: Latest version of Chrome for windows

Using the Waterbury dataset:

Default settings when running the job.

I’ve noticed this issue yesterday; it seems a problem with older versions of docker and images built with the newer buildx feature of docker. Are you able to use docker desktop instead of docker toolbox?

Thanks for the tip, I have reverted to docker Desktop. Currently seems to be running smoothly. Now I just need to figure out how not to run over the measly 16 GB I have access to on my box :wink:

I’m also attempting to fix this at the image level, there should be an updated docker image within ~10 hours.
