Hi,
This limit and many others are adjustable with the sysctl command and the /etc/sysctl.conf file read at boot time.
On my 10.11 workstation, kern.ipc.somaxconn (number of connection allowed) is 128 but I read that the freebsd kernel allows 1.5X before refusing the connections, darwin may does the same thing.
This reminds me I should check these on my servers...
