Hi list, I wrote about this before: my first map in the mapset, 63240001.img, is missing. I tracked this down to revision r1363 (which is a merge from the mapset branch) and today even further tracked it down to revision 1323 within the (deleted) mapset branch. However, I can't find any clues in r1323 as to what causes this. Further experiments showed even weirder results: as I compile my maps from a template.args file, it showed that having 63240001-63240009 in there would give me the correct map; having a 10th file in there made the first one missing. (Currently, while compiling the Netherlands, my template.args file has 14 entries. Any number above 9 makes the first one disappear). And indeed, when I duplicated the first file like so: mapname: 99999999 input-file: 63240001.osm.gz mapname: 63240001 input-file: 63240001.osm.gz mapname: 63240002 [...] ... the map would be correct (with the void 99999999 probably missing, and 63240001 included). Now I'm stumped. Would anyone know what's going on here? I thought of a race condition and removed the --max-jobs option, but that makes no difference. Best regards, Valentijn
