I am doing load testing of neo4j with JMeter, for 200 concurrent connections neo4j is working fine. But whenever I am increasing the load over server by increasing the number of concurrent connections from 200 to 300 or 400 or 600 in that case neo4j is throwing error “ Unable to acquire connection from the pool within configured maximum time of 60000ms”. Even I have checked within neo4j.properties file to change default connection timeout from 60s to more. But there is no such timeout attribute within neo4j.properties file which default value is 60s.
Can someone please help me out here how to fix this timeout error.
Neo4j version : 4.1.0 enterprise
