Idle cypher-shell process in redhat linux using high cpu

[rubensselvakuma]

Hi,

We are experiencing high cpu usage when the cypher-shell process initiated by users are not closed properly because of unix session timeout, please can you help fixing this.
Is there a way we can set idle session timeout at client end?

Linux Machines: AWS ec2 instances with RHEL 8.
Neo4j: 4.4.3

Issue Scenario:
User establish a ssh connection from jump host to the AWS ec2 instance and use cypher command to connect to the neo4j DB.
Once AWS ec2 ssh/ssm connectivity is closed the cypher-shell process remains active and started to consume more cpu resource (one complete core), more than one such process started to saturate cpu resource(cores).
