Thanks, there seems to be some known problems with lucene on NFS. If you're calling getNodes on a non-existing index then I committed a fix for that (added one extra null check), but if that index should exist it could just be that lucene is having trouble with NFS.
I'll look into this further to see if there's something to be done to help lucene in these areas. 2009/11/18 Jakub Kotowski <jakubkotow...@gmx.net>: > Mattias Persson schrieb: >>>> After playing with it more, the culprit seems to be not the symbolic >>>> link but the local drive :-/ When I delete the neo4j directory with the >>>> db and start the application from the local drive then I'm getting the >>>> NPEs - even if I shut the server down and start it again.
