New output when running dispatcher: File_Error 0 Success
/home/bvogelgesang/mnt/osm-db-disk/nodes.bin.idx File_Blocks_Index: Data file
size does not match block size

sort of, yes. This means that the data file has been for whatever reason
truncated. The data file, here "nodes.bin" must have a size that is a
multiple of 65536, because the Overpass API always writes blocks that
are a multiple of that.

In the end this means we need to figure out what has happened to that
file, fix that problem, and then redownload a clone (or make a database
from a planet file). The file as such is probably now useless, because
it is lacking some data.

Given that this has been an error condition not checked for yet, it is
well possible that osm3s_query simply got over that error and would have
crashed only when trying to read the now missing data. Or not crashed at
all and silently have not delivered all objects.

Given your earlier mail of an empty result, this would fit into the picture.

I'm sorry for these bad news.

Best regards,
