I didn't get much out of the debug file after I tried running the dispatcher,
below is my output

[ bvogelgesang@osm-vm:~/mnt/osm-db-disk ]$ $EXEC_DIR/bin/dispatcher
--osm-base --db-dir=$DB_DIR
Segmentation fault (core dumped)
[ bvogelgesang@osm-vm:~/mnt/osm-db-disk ]$ cat nodes.bin.debug
DEBUG a
DEBUG b
DEBUG A
DEBUG B
DEBUG C

Was I supposed to do anything else to populate that file?

Much appreciated
Brian

patching like you said and respond with results. Much appreciated

This is an excellent idea. From the insight of the strace, I have been
able to understand that dispatcher crashes in a different location than
conjectured.

Please remove the patch. I don't know what has gone wrong, could be
something like missing the right line number by one. I have prepared
instead a special dist with more debugging output:

https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdev.overpass-api.de%2Freleases%2Fosm-3s_v0.7.55.debug.tar.gz&amp;data=02%7C01%7Cbvogelgesang%40rightpoint.com%7C95f946848c344ef2d77808d783848cea%7C5fbbce2ac3e64b5ea51f222674fdb44d%7C1%7C0%7C637122477663611955&amp;sdata=64VXIrpKmvyB8NqpiDrxtggWvw0j0scUTTZsfdt%2F8f8%3D&amp;reserved=0
Please use this instead of the osm-3s_v0.7.55.7.tar.gz for the moment
being.

There should appear a file
$DB_DIR/nodes.bin.debug
Could you please send the content of the file (the list does not process
attachments). The first 4K or so should suffice - I expect it to be of
only a few hundred bytes. This is a special log around the expected
crash location.

Best regards,

Roland
