The warning with omitmetadata=true seems to be a known osmosis warning 
without any effect. I have just ignored it.

As it is documented the idTrackerType is an option that can be used to 
optimize the used-node and used-way implementation. If you give osmosis 
more memory it will definitely work without the option. But in some 
configurations it might be faster and less memory intensive.
