"Out of memory" crash and a little question

[ItWasLGS]

Hi,I met some questions when exploring your knowledge graph as I list below:

Firstly,as I finshed the building step(for docker container),I excuted some lines in Cypher to test the knowledge graph.
But after the line "match data=(n{name:"cancer"})-[*1..2]->(m) return data" input,I just got my neo4j crashed and the error code"out of memory".
Even if I rebuilt the docker container with "docker run -d --name ckgapp -p 7474:7474 -p 7687:7687 -p 8090:8090 -p 8050:8050 --env=NEO4J_dbms_memory_pagecache_size=20G --env=NEO4J_dbms_memory_heap_initial__size=10G --env=NEO4J_dbms_memory_heap_max__size=20G docker-ckg:latest",it remained the same.

Secondly,I am curious about whether there would be any node or relationship about time infomation in your graph,while I got nothing from your property key"timepoint".So I wonder if there exists such information in CKG.

I would be very appreciated if you can help me with those questions and longing for your reply.
