6.8. Adjusting the connection backlog size
The listen service sets the number of sockets available to receive incoming connections. The nsslapd-listen-backlog-size value sets the maximum length of the queue for the sockfd socket before refusing connections.
If your IdM environment handles a large amount of connections, consider increasing the value of nsslapd-listen-backlog-size.
