Neo4j Embedded database hangs after abnormal application termination

Question

Neo4j Enterprise allows you to run multiple Neo4j instances in a cluster providing you high availability and scale out for reads. To survive n failures at the same time you need 2n+1 instances.

In case of a unclean shutdown, the expected behaviour is an automatic recovering operation upon next startup (which might take some time). In the last few years I've never experienced Neo4j in a non-recoverable state after a unclean shutdown.

For embedded use cases be sure to call gdb.shutdown() in a JVM shutdown hook.
