Good day everybody,
I had a question about a project I’m currently processing. For this I’m using a 32GB Linux VPS, running WebODM (machine A). For large(r) projects, let’s say more than 400 images, I configure another (temporary) VPS (machine B), install NodeODM on it and add this node into WebODM on the 32GB machine. When the project is finished I suspend the temp machine B.
Usually this works (very) good. For a current project, 1595 M3E 20MP images, I configured a larger VPS (machine B) and added this as an extra node into Machine A. Very soon after the processing starts I see an error:
`[INFO] Loading 1594 images

I made the assumption it might be caused by (some) wrong information in the EXIF headers of one or more picturs, therefore I made a small selection of images, only 138 images.
I processed this smaller subset
- Machine A –> local node (node-odm-1)
- Machine A –> Node machine B (256GB RAM)
The strange thing is… the smaller dataset is processed correctly on the 32GB machine, but gets an error on the 256GB machine.
Both working on the same dataset, preset and image count.
Machine A –> WebODM 2.8.4
NodeODM Machine B –> latest
The error code on the smaller subset then reads:

===== Done, human-readable information to follow… =====
[ERROR] Uh oh! Processing stopped because of strange values in the reconstruction. This is often a sign that the input data has some issues or the software cannot deal with it. Have you followed best practices for data acquisition? See ` https://docs.opendronemap.org/flying/`
100 - done.`
Does anybody have an idea what might cause this? Thanks a lot!
