Troubleshooting

GraphDB Configuration

If you get the following error, you need ot increase teh memory used by Java for running GraphDB, see below:

Query evaluation error: Insufficient free Heap Memory xxxMb for group by and distinct, threshold:xxxMb, reached 0Mb (HTTP status 500)

• Increase memory for Java:
  • Update the GraphdDB application cfg file
  • Usualy it is here: /Applications/GraphDB Desktop.app/Contents/app/GraphDB Desktop.cfg
  • Add or update the following lines to have 20G memory:

    [JavaOptions]
    ...
    java-options=-Xms20G
    java-options=-Xmx20G
    ...
