I have a large .osm file (300MB) which I created using public data and a homemade script. I can just barely open it in JOSM on my computer (it takes about 20 minutes to load, and then is too way slow to edit reasonably). JOSM gives no errors when I do this, and the data looks as expected, so I think my .osm file is error free.
Can someone give me instructions about the best way to upload this, seeing how JOSM is impractical for this purpose? I also tried bulk_upload.py, but it grabs all my memory and swap space and the system freezes.
I could also send the file to someone (~35MB bzipped) and they could upload it, if they think they can do it better than me.
