Hello Michael, I have upgraded my server to 4GB total RAM and I have allocated minimum 256 MB and maximum 2GB RAM to neo4j . But still I got error and today it terminated by saying "JAVA Heap out of memory". moreover it is not exhausting complete 2 GB ram i saw it using HTOP.
I dun know why it is happening any suggestion please.
