Editing the complete Iceland dump (http://osm.nix.is/latest/Iceland.osm.bz2) 2. Had just uploaded to http://www.openstreetmap.org/browse/changeset/2721542 and left it open 3. Pressed upload but something in the UI lagged so the upload commenced instead of giving me a changeset dialog (I may have pressed enter when the upload dialog was still waiting to appear) 4. Uploaded an invalid node as a result 5. Deleted it 6. Opened a new upload dialog to upload this: http://www.openstreetmap.org/browse/changeset/2721633 7. While doing #6 JOSM's CPU usage was >100%. Usually around 115% using around 900MB of resident memory: {{{ PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 20286 avar 20 0 1234m 887m 5404 S 126 46.9 7:33.87 java }}} Both of the changeset comments were in the US ASCII subset of UTF-8 so I don't know if this is related to #3371 Here's the output of kill -QUIT when JOSM was consuming all that CPU: {{{ 2009-10-03 11:03:32 Full thread dump
