Web services (client on WLS) <- https -> Load balancer <- https -> Apache Proxy server <- http -> Web services (host on WLS)

When the client accesses the web services, the number of connections in CLOSE_WAIT status keep growing on the web services client. All the CLOSE_WAIT connections are between:

Web services (client on WLS) <- https -> Load balancer
