If you encounter the above mentioned issue then perform the following  actions :

1. Check the values set for below parameters from neo4j.conf file :

   dbms.memory.heap.initial_size
   dbms.memory.heap.max_size
   dbms.memory.pagecache.size

2. 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 "neo4j-admin memrec --memory=32G".

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..
