Error: java.lang.OutOfMemoryError: GC overhead limit exceeded

Please try to start the Accelerator with the following: java -Xmx1024m -jar flexmonster-proxy-mondrian.jar where -Xmx<size> is the maximum Java heap size.

Error: java.net.UnknownHostException: <hostname>: <hostname>: Name or service not known

Some enterprise environments do not allocate DNS names to their devices – that results in an UnknownHostException, often after a lengthy DNS lookup attempt. Here are few possible actions:

  • the first suggestion is to ignore the message. Given that error the application is working fine and the message is only seen in the logs. Please try to open your browser and navigate to the following URL: http://127.0.0.1:50006/ or http://localhost:50006/. There should be a message “Flexmonster Data Speed Accelerator for Pentaho Mondrian”.
  • or you can try to add the following record to the hosts file: 127.0.0.1 <hostname>
