Splunk DB Connect: How to fix Java Bridge Server error "Unable to listen on localhost:17865: java.net.BindException: Address already in use"?

This is the error I see in _internal index logs

main:FATAL:JavaBridgeServer - Unable to listen on localhost:17865: java.net.BindException: Address already in use
java.net.BindException: Address already in use
    at java.net.PlainSocketImpl.socketBind(Native Method)
    at java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:376)
    at java.net.ServerSocket.bind(ServerSocket.java:376)
    at java.net.ServerSocket.<init>(ServerSocket.java:237)
    at com.splunk.bridge.JavaBridgeServer.run(JavaBridgeServer.java:140)
    at java.lang.Thread.run(Thread.java:745)

Please suggest how it can be solved

Hi Ashish_Singla,

the port 17865 is already taken by another process. Change it in the java.conf http://docs.splunk.com/Documentation/DBX/1.1.6/DeployDBX/javaspec inside the DBX app.
It should be located at $SPLUNK_HOME/etc/apps/dbx/local/

cheers, MuS

Thanks,
The problem is resolved by specifying a new port for java bridge.
