Hi,
I've been happily using neo4j for the data store for our project for some time
now, but after working with b-9 for a couple weeks in development I've run into
the following problem during startup:
2009-09-10 12:09:35,926 ERROR :

To be fair, though, on the previous run I terminated the running process when
code outside neo was churning because I had started it by mistake and was
impatient :). I'd done this many times before in development on both this
version and previous releases and never ran into this problem. The store size
is roughly 250MB. I tried deleting the transaction logs but no joy :(.
This looks like some kind of assertion error, though, so I thought I'd let you
guys know in case there is something serious going on here...
Thanks,
Justin
