neo4j creating multiple nodes json - json

Question

Please let me know where I am going wrong
I am using neo4j to store my routers interface and link information. The link is to be created between 2 interfaces.
I have successfully created nodes and interfaces but finding issues in creating links.
This is the query I use to create link
MATCH (I:Interface), (I2:Interface)
FOREACH(p in FILTER(z in {props} WHERE z.OrigIPAddress = I.IfIPAddress or z.TermIPAddress = I.IfIPAddress) |
MERGE (I {IfIPAddress:p.OrigIPAddress})-[r:link]->(I2 {IfIPAddress:p.TermIPAddress})
ON CREATE SET r = p
ON MATCH SET r = p)
I have an array of maps called props which I am passing in the json as params which contains the properties of link i.e OrigIPAddress (Originating interface IP), TermIPAddress (Terminating interface ip).
In the foreach I first filter all those link which have their source or destination interfaces already present. Now after doing this I am creating links out of the props.
When I run this it runs properly but no links are created. There are both source and destination interfaces present.
EDIT 1:
I modified the query and when I run this query
MATCH (I:Interface), (I2:Interface)
FOREACH(p in FILTER(z in {props} WHERE z.OrigIPAddress = I.IfIPAddress and z.TermIPAddress = I2.IfIPAddress) |
MERGE (I {IfIPAddress:p.OrigIPAddress})-[r:link]->(I {IfIPAddress:p.TermIPAddress})
ON CREATE SET r = p
ON MATCH SET r = p)
I do not get ant response back from the neo4j and in neo4j web console I can see this meesage
"Neo4j disconnected, check you socket..."
Here are the logs

Let me know where I am I going wrong.

Answer 1

Is this closer to what you are trying to do?
MATCH (I:Interface)
FOREACH(
p in FILTER(z in {props}
WHERE z.OrigIPAddress = I.IfIPAddress or z.TermIPAddress = I.IfIPAddress) |
MERGE (I)-[r:link]->(:Interface {IfIPAddress:p.TermIPAddress})
SET I.IfIPAddress = p.OrigIPAddress, r = p
);

Answer 2

Finally after googling I found the issue.
Its server timeout. Since the query is taking some time to execute, the server is timing out and sending a response.
I increased the timeout and it worked
Here is the reference on how to increase it.
