[osmosis-dev] Crash on processing nodes?

[Brett Henderson]

Hi Simon,

The duplicate node entry could be caused by a couple of reasons:

1. There were bugs in some builds of Osmosis 0.31.1.  Is there a reason
you're using 0.31.1?  The latest stable version is 0.32.  You can get it
here:
http://wiki.openstreetmap.org/index.php/Osmosis#Latest_Stable_Version

2. Are you using replication diffs instead of daily diffs?  These diffs can
contain multiple version of the same entity because they are full history
diffs.  The delta style daily diffs are more appropriate for patching osm
files.
