[Eran Hazout]

Hi all,

I just installed Neo4j 3.0 through apt-get on ubuntu 14.04. after rebooting the server I see that neo4j is running on "htop" but when I do #service neo4j status I get this:
Neo4j is not running

Tried to exec: #service neo4j restart and I get:

Neo4j not running

Starting Neo4j.

/usr/share/neo4j/bin/neo4j: line 149: /var/run/neo4j/neo4j.pid: No such file or directory

and neo4j.log show this exception:

I didn't find anyone on google that experience the same problem so I created a brand new ubuntu server and tried again.. unfortunately I get exactly the same bug.

btw, running on java 8:

java version "1.8.0_91"

Java(TM) SE Runtime Environment (build 1.8.0_91-b14)

Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode) 

Any idea how to fix or what I did wrong?

Thanks

Hmm,

are you sure there is no other process accessing the database?

can you try to manually start and stop the neo4j server?

Perhaps it's something in the shutdown sequence that just does a hard-kill?

Steven, do you have any ideas?

Michael
