The server suddenly stopped to work and on restarting it gave the following error. Couldn't find anything related to this online. Any idea what is wrong and how to resolve this?

It looks like you've messed up your datastore e.g. by a unclean shutdown. To recover try the following procedure:
graph.db folder, make sure that you have a valid backup copy e.g. by tar -zcf <path>/graph.db.tar.gz data/graph.db. rm data/graph.db/nioneo_logical.log.active. NB: this operation might be harmful.
