Quite often I notice 'Service Unavailable' for Elasticsearch when accessing Kibana. I SSH into all of the nodes and start investigating logs. Most frequently, it is a result of this file " **es**.tmp" The error in the logs is as follows :: Exception in thread "main" java.nio.file.FileAlreadyExistsException: /data/elasticsearch\_data/TrainingProd/nodes/0/ **es**.tmp at sun.nio.fs.UnixException.translateToIOException(UnixException.java:88) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:102) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:107) at sun.nio.fs.UnixFileSystemProvider.newByteChannel(UnixFileSystemProvider.java:214) at java.nio.file.Files.newByteChannel(Files.java:361) at java.nio.file.Files.createFile(Files.java:632) at org.elasticsearch.env.NodeEnvironment.ensureAtomicMoveSupported(NodeEnvironment.java:794) at org.elasticsearch.gateway.GatewayMetaState.(GatewayMetaState.java:82) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at \<\<\>\> at org.elasticsearch.node.Node.(Node.java:200) at org.elasticsearch.node.Node.(Node.java:128) at org.elasticsearch.node.NodeBuilder.build(NodeBuilder.java:145) at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:178) at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:285) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35) To fix this, I have to rename that file to something else, such as adding .old to the end. Then I restart Elasticsearch and the stack is fine again and accessible. Does anyone know anything about this?? Is this a known ES bug? Version of ES :: 2.2.1 ---

Hi @Michael1, I dug around in the code and I think this is a bug. I am just not sure were the problem occurs exactly. If this problem happens again, can you please check whether there is also a file called ` __es__.final`? Can you also check whether there is any related exception trace before this one (e.g. that a file could not be deleted)? It would be great if you could look up this information and open a ticket on Github then. Daniel ---

I can check the next time it happens. Is the information I provided above enough to open an issue on Git? ---

Hi, it would help greatly if we know ` __es__.final` also exists and also if there are any exception traces before the one you have provided (it is possible that either file deletion failed before or the problem occured when ` __es__.final` was first referenced). Daniel ---

Do you know if this continue happens with elasticsearch 2.4.1. Because I have the same problem with elasticsearch 2.4.1: bash-4.1# service elasticsearch start Starting elasticsearch: Exception in thread "main" java.nio.file.FileAlreadyExistsException: /data/elasticsearch/marta/nodes/0/ **es**.tmp at sun.nio.fs.UnixException.translateToIOException(UnixException.java:88) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:102) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:107) at sun.nio.fs.UnixFileSystemProvider.newByteChannel(UnixFileSystemProvider.java:214) at java.nio.file.Files.newByteChannel(Files.java:361) at java.nio.file.Files.createFile(Files.java:632) at org.elasticsearch.env.NodeEnvironment.ensureAtomicMoveSupported(NodeEnvironment.java:794) at org.elasticsearch.gateway.GatewayMetaState.(GatewayMetaState.java:82) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:422) ---
