Can you try to set a higher ulimit for open files?

[Neo4j] Error importing data into neo4j with py2neo version: 3.1.2

[Jon Endre Hausberg]

Hi,

I am using  py2neo version: 3.1.2 to ingest data into neo4j.

 

After a while (about 4 million nodes 5 million relationships) I get Error 
10055 an operation on a socket could not be preformed because the system 
lacked sufficient buffer space or because a queue was full. 


On Linux I get an error to many files open.

 

I am using:

 

graph.run(query_sting, data)

 

And this for transactions:

for i in data:

tx.run(query_string, i)

count +=1

 

if count == 1000:

tx.commit()

tx = graph.begin()

count = 0

if count > 0:

tx.commit():

 

Is this way of execute statements wrong? Is there a way to close the 
connection after the transactions?


Best regards

Jon
