had a relatively small database that was working fine.
then the server spiked at 99% cpu for an hour. only thing i could do is terminate the process.
now the server will not start providing the following error.
Starting Neo4j Server failed: Error starting
org.neo4j.kernel.EmbeddedGraphDatabase, c:.......
i have since rebooted the machine.
i am running 2.1.5 community edition on a windows server.
Any help would be greatly appreciated.
It sounds like your data directory is corrupt. Go into db/data and rename graph.db to graph.db.old, then restart.

I was given a graph db I must open with Neo4j. Installed community version Neo4j-2.2.0-M02 on Win7 Ultimate laptop successfully. When I tried to start the server, after pointing to the graph db, I get the following error:
Starting Neo4j Server failed:
Component org.neo4j.server.database.LifecycleManagingDatabase#325ce05c was successfully initialized, but failed to start. Please see attached cause exception.
Logged in as windows local admin. Windows FWall is off. There's no antivirus SW installed on the machine. Local admin has full perms on entire root drive. When I point to the default db, Neo4j server starts normally and I can browse http://localhost:7474/ without a problem.
Any lead will be appreciated.
The aforementioned error message was the result of using a Neo4j version different to the one the graph db was originally developed. In particular, the original graph db was developed in ver 2.0.4 Community that due to my lack of knowledge I was trying to run on an installation of Neo4j ver. 2.2.0-M02 (for development only).
The code owner enlightened me to the fact and an attempt to bring up the graph db on ver. 2.0.4 Community was successful.
Thanks for your support.
Delete the folder "c:\Users\Yourname\MyDocuments\Neo4j"
I removed the plugins that were loaded from <NEO4J_HOME>/plugins as they were also loaded from under <DATABASE_HOME>/plugins
Well, I just started neo:, 2.1.3 on a Ubuntu machine:
pdipietro#CUC-N4J-V4-0-0:~/gsn$ rake neo4j:start
Starting Neo4j development...
pdipietro#CUC-N4J-V4-0-0:~/gsn$
Now, if I open it in the browsed I got the following error:
But if I click the webadmin in the classicUI it start correctly
and run, with the expected results.
Tis is the config and there are plenty of GB of mmory.
Any Idea?
Thank you in advance
Paolo
Thank you for bot suggestions, but I'm not able to resolve:
http://localhost:7474/browser is disconnected from Neo4j, while
http://localhost:7474/webadmin/#/console/ runs fine
I wasn't able to discover any evident config flaw.
Where are the two different config files?
i just tried to access Neo4j through Gephi. After that when i tried to access Neo4j, it throw the following error. I'm using Neo4j 2.0.1.
Error:
Starting Neo4j Server failed: Error starting org.neo4j.kernel.EmbeddedGraphDatabase, C:\Users\Sakthi\Documents\Neo4j\default.graphdb
Make sure you don't have another Neo4j server running against the same folder
Make sure the user running gephi has read/write access to that folder
Look for the messages.log in that folder, and see if you can find any exceptions
Yesterday neo4j was working as expected, and today it isn't. I'm getting the following error:
unknownc8e0eb17b72f% ./bin/neo4j status

launchctl start error: Bad file descriptor
Running ./bin/neo4j console does not cause problems and I can see my graphs using the web tool on my localhost.
Perhaps related, I'm using jexp's batch-import tool to import my data and the labels aren't coming through.
I've tried restarting, deleting and redownloading, etc. I'm using the 2.0 RCI version of neo4j.
I saw the related questions from ~6 months ago but with the new 2.0 build and the fact that following the advice on that thread didn't work for me made me want to open a new question.
You have it installed as a service. See this answer for how to uninstall:
"launchctl start error: Bad file descriptor" when trying to start Neo4j server
I've installed the MySQL workbench version 5.2.34 and having problems creating a local connection. I'm getting an error saying "Can't Connect to MySQL Server on 127.0.0.1'(10061)" when i try connecting to Localhost on Port 3306. I tried restarting the service but i don't have the option to stop/start/pause or resume using Windows 7. The status is just set to "starting". I also tried "net stop mysql" from the command line in DOS but get the following error: "The service is starting or stopping. Please try again later"
Does anyone know if this is another bug in the Workbench or is there a quick solution to get around this?
You can restart mysql from services. Also, check error log (by default, on Windows 7 machine it's under ...ProgramData\MySQL\MySQL Server [version]\data
Sounds like a problem with MySQL itself starting up. You may have to kill the mysqld process if nothing else gets it into a started or stopped state, and then investigate the .err logs in your data directory.
This solution uses the window's mysql installer which you have used to install your MySQL.
Even though this post is very old, I have wasted around 2 hours and hence want to post this so that it can save someone else's time.
I have tried every other way of restartring the service, but mysql service just wont start.
Start your windows mysql installer. For me it was "mysql-installer-community-8.0.20.0"
Then remove/uninstall the SQL Server and remove all configurations
Manually delete the SQL Server folder from "C:\Program Files\MySQL\MySQL Server 8.0."
Start your mysql installer again and install the SQL Server again
You can check now that the MySqL Server has started.
