Make sure that  **dbms.memory.heap.max\_size**  and **dbms.memory.pagecache.size** is not more than 50% of your RAM size. 3. You can also run an optimization test (**memrec**) that will recommend memory allocation and database settings for you. Please follow the below steps. i. Open command prompt. ii. cd %PROGRAMFILES%\CAST\ImagingSystem\neo4j\bin iii. Run the command **&#34;neo4j-admin memrec --memory=32G&#34;.** 4. Settings will be recommended as per your memory configuration. For example, below screenshot shows the result for same command in machine that has 16 GB RAM :  1.  2.  5. Restarting the Neo4j service may not adequately reflect the configuration changes made. It is essential to update the service as well.  To update the service, run **bin\neo4j update-service**. Then restart the service to run it with the new configuration.   For  Docker restarting the container should be enough.. 6.
