[OSM-dev] osmosis problem with truncate

[Stephan Knauss]

Hi,

is this a bug or am I using it wrong? Sporadically osmosis throws an 
exception. I do not understand the reason because I wanted to clear the 
db before an import using the truncate task.

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

and throws this exception:
