personal PageRank Thrown 'OutOfMemoryError: unable to create native thread:' under normal use case #139
Description
continue with issue #132
In my real use case, I first create an In-memory projected graph which have 6017 nodes and 37819 relations.
Then, I run personal PageRank only 3 times that each time with 2276 nodes as [sourceNodes].
Still face the thread issue when threads come to 4095.
what can I do for this situation ?
I am suffer from this error for a long time....
below are my cypher queries
CALL gds.graph.create(
'UP',
['User', 'Post'],
{
Action: {
orientation: 'UNDIRECTED',
properties: 'weight'
}
}
)
MATCH (sources:User)
WITH sources
CALL gds.pageRank.stream('UP', {
sourceNodes: [sources],
relationshipWeightProperty: 'weight',
concurrency: 1
})
YIELD nodeId, score
WITH sources, gds.util.asNode(nodeId) as nodes, score
WHERE (nodes.pid IS NOT NULL) AND (NOT (sources)-[]->(nodes))
RETURN sources.uid as source, nodes.pid as pid, score
ORDER BY score DESC
It still throw the same error.
