icm/listen_queue_len
During connection establishment, the operating system must keep requests in a queue. This parameter specifies the maximum number of requests that can have this status at any one time.
If the network queue is full, the system rejects any additional connection requests without notifying the sender.
Operating System Restrictions
This parameter is handled differently by different operating systems. The maximum value for 4.2 BSD was 5. Today’s systems support various values. If the operating system’s maximum value is exceeded, the operating system reduces the parameter value to the maximum supported value. See also the description of operating system call
