When is this happening, during the batch import or after for a query?
It sounds like an incomplete shutdown. You need to make sure you issue a
.shutdown to the db (batchinserter) and give it time to complete, it can
take awhile.
Make sure you have write permissions for the directory. And always start
with a clean directory (delete any previous datastores) for a Batch Insert.
If you are running it under lein you need to use ^:replace for :jvm-opts or
it will slow things down considerably.
Here is what I am using in my project.clj, they are based off of what Neo4j
uses from the command line and some benchmarks. You may want to reduce the
-Xms and -Xmx. What are you giving Neo4j for memory as well when you start
it up? It uses it's own memory allocation and can exceed what you give the
JVM, so you want to give Neo4j more and clojure less, and want both to be
less than your total ram so you do not hit swap space (which will slow it
down again too).
:jvm-opts ^:replace [
"-Xms6G"
"-Xmx8G"
"-XX:+UseConcMarkSweepGC"
"-XX:+UseBiasedLocking"
"-XX:+AggressiveOpts"
"-XX:+UseFastAccessorMethods"
"-XX:+UseCondCardMark"
