[OSM-talk] Osmosis heap space, tuning not working

[Michal Migurski]

I'm running Osmosis on a complete recent planet, and seeing memory errors.

My ~/.osmosis file looks like this:

	JAVACMD_OPTIONS=-server
	JAVACMD_OPTIONS=-Xmx16G

…based on advice from http://wiki.openstreetmap.org/wiki/Osmosis/Tuning. 16GB is half the RAM in this 64 bit machine.

Here's the error where it blows up:

	SEVERE: Thread for task 1-rb failed
	java.lang.OutOfMemoryError: Java heap space

This is the command I'm running:

	osmosis --rb planet-120920.osm.pbf \
		--log-progress --tf accept-ways 'highway=*' --tf accept-relations 'network=*' --used-node \
		--tp user=osm database=planet_osm \
		--wp user=osm database=planet_osm

According to the progress log I get all the way through the relations before it fails. There's not other giant processes running. What is going on?
