Hi all! I'm using python embedded in order to classify all the nodes in a neo4j graph previously labeled with properties. The graph is about 3.9GB with 7M nodes and 30-40M relationships. I've two questions: 1- the program worked correctly for hours then crashed suddenly with this error: Traceback (most recent call last): File ''assegnaCategoria.py'', line l4, in <module> for n in db.nodes: File ''/usr/local/lib/python2.6/dist-packages/neo4)/ _ init _ .py'', line 44, in _ getitem _ return sel_.get(items) File ''/usr/local/lib/python2.6/dist-packages/neo4)/ _ init _ .py'', line 6l, in get rethrow current exception as(KeyError) File ''/usr/local/lib/python2.6/dist-packages/neo4)/util.py'', line 76, in rethrow_current_exception_as raise ErrorClass(msg) KeyError: u'Node[9327924]'
2-the program is very slow.I started it at 18 pm end it crashed at ~65% of the work at 4 am It only reads the database, never changing it, is there a way to set it to use the cache intensively? I would put it in /dev/shm/ but my RAM is 3GB and the database is bigger. The code is this http://codepad.org/leSwqhnc Cheers, Jacopo _______________________________________________ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
