What steps will reproduce the problem?

Start JOSM
Open reverter plugin
Insert changeset 26757923
Wait up to 15 (or more) minutes since there is a lot of data

What is the expected result?

Should successfully download past changeset data without warning messages.

What happens instead?

A error message appears in roughly half of the attempts and every time at different points.

It is always a 500 Internal Server Error.

'''If any option is chosen an error message appears stating it's not possible to complete the request.
Please provide any additional information below. Attach a screenshot if possible.'''

This is (unfortunately) normal currently - they are just too big and complicated and in order to protect server resources we have a timeout in place which is what you are seeing.

Hopefully one day the relation/full call will be moved into cgimap and we'll be able to handle larger relations.

I see, should this ticket be closed since it's an already known issue?

relation/full is in cgimap, TomH presumably means the changeset download API call.

It's an invitation to upload "unwanted" stuff and give people who have to fix it a hard time. What would be the solution when this happens?

Maybe restrict the number of objects in one changeset to what can still be downloaded with /changeset/#id/download. Or add a call to split the download into several requests (like /trackpoints?bbox=left,bottom,right,top&page=X)
