Print | Individual message | Show original | Report this message | Find messages by this author

I am using EC2 with ubuntu 12.04.
I already have neo4j 1.6.1-community edition running on my ec2 production
server and on my local machine with the same configurations.

I setup a test server today copied neo4j "data" folder from production to
test ec2 instance and installed neo4j. but when i try to start, it gives
error:-

>>sudo service neo4j-service start

WARNING: Detected a limit of 1024 for maximum open files, while a minimum
value of 40000 is recommended.
WARNING: Problems with the operation of the server may occur. Please refer
to the Neo4j manual regarding lifting this limitation.
Starting Neo4j Server... process [22796]... waiting for server to be
ready...................................................................... ...................................................
BAD.
 another server-process is running with []

I have already increased in the file limits ass metioned in the docs. I
have tried removing and installing again.

Is there something I am missing here?

If you're sure that there is no other server running,(check with ps) you can remove the lockfile in the db directory.

The presence of the lock file isn't preventing a startup though, it's
whether it's locked or not. So deleting that file should never ever be
required.

Last time, i checked with ps aux | grep neo4j.... saw one process, killed
it and it started working.
Now I am again setting up a new server, I followed exactly the same steps
like earlier,
this time I am getting this error:-

mnt/neo4j-community-1.6.1/data$ sudo service neo4j-service start

WARNING: Detected a limit of 1024 for maximum open files, while a minimum
value of 40000 is recommended.
WARNING: Problems with the operation of the server may occur. Please refer
to the Neo4j manual regarding lifting this limitation.
Starting Neo4j Server... process [18187]... waiting for server to be
ready...................................................................... ...................................................
BAD.
 another server-process is running with []

I tried removing the lock file too, still getting same error.

What Neo4j version are you using? Could you try with Neo4j 1.8?

I am using 1.6.1 community edition. The same configuration is working on a
different aws server. Our current implementation has been developed on
1.6.1 Will there be any problems with 1.8 ? Are all cypher queries used in
1.6.1 supported in 1.8?
