Database 4.4.17 Graph Data Science Library 2.3.1 Java 17.0.5 Mac OSX 14.1.2 Neo4J Desktop 1.5.9 Total memory 40G dbms.memory.heap.initial_size=15G dbms.memory.heap.max_size=15G dbms.memory.pagecache.size=16G

Graph 883 nodes - 1 type 993 relationships - type Connects and sees and sees nodes and relationship through Graph Data Science Playground

Select Degree centrality with default settings. click OK. Never completes just runs. Have left for 30 min. I have tried other algorithms such as Label Propagation with similar results Additionally after closing window I cannot stop database after running Graph Data Science Playground algorithm. It stays in "stopping" mode for 2+ hrs.

I need to force quit Neo4J and restart computer.

I have another database Neo4J 5.14.0 Graph Data Library 2.5.5

Which shows similar issues.

Additionally and possibly related I hear fan kick in and when I check with Activity Monitor it does two quick scans and then locks up. Using it does two scans and then lists processes by CPU usage. It never gets to the point of listing processes. I also have to force quit. Additionally from Bloom I get similar issues though it shows an error message of "poor connection retrying" I have deleted and reinstalled plugin. Similar result.

Any remedies? Andy

I think I found a solution. Upgraded database 4.4.17 -> 4.4.28 This allowed version 2.5.6 of GDS to be installed. Previous delete and reinstall without database upgrade only showed 2.5.5 With 2.5.6 the library works as expected Andy
