Unable to run pagerank algorithm on neo4j-community edition for ~40M dataset

Neo4j Graph Platform Procedures & APOC

Hi,

I am trying to run pageRank algorithm for a sample graph dataset
Twitter-2010 dataset.

I have a 64GB RAM linux server, where I have set up neo4j using the Unix tar.gz available (community edition)
Importing the data was done in good time.

But when I try to run the pageRank algorithm on this data I am getting this alert in debug.log file.

2019-09-17 11:25:31.847+0000 WARN [o.n.k.i.c.VmPauseMonitorComponent] Detected VM stop-the-world pause: {pauseTime=1330, gcTime=1390, gcCount=1}

And the process isn't completing and gets into a hung state.

I have tried different variations for the heapsize to tweak performance but am never able to complete the process.

Have referred to this link for reference:
