Osmosis has two types of tasks under the covers, active tasks which run in their own thread, and passive tasks which are called from other task threads.
In your case the active --truncate-pgsql and --fast-read-xml (connected indirectly to the --write-pgsql task) tasks are both executing in parallel which means that the --truncate-pgsql and --write-pgsql task both access the database concurrently. There is no way to tell osmosis to finish --truncate-pgsql before starting --fast-read-xml. You'll have to run them separately. > Osmosis is called like this: > > osmosis --truncate-pgsql database=db user=pg --fast-read-xml-0.6 > file=f.osm --buffer --write-pgsql user=pg database=db > > _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
