I have installed neo4j 4.3.3 in 4GB RAM server. I had given memory allocations as suggested by neo4j-admin memrec .My DB Size nearly 1 GB .There are some miniservices are running in the server
I had given 1900m for heap and 512m for page cache as suggested .But still db stops daily a time unknowingly .I had gone through debug.log No evidence of exceptions or errors present
It has only below statements regarding checkpointing and pruning

My Questions are
- Why does the DB Stops?
2)Does the log pruning induces the db to stop
- if 4GB is so low for 1GB data DB how much the RAM Size should be and how much the HEAP,PAGE CACHE Size should be??
Thanks in advance
