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...

Samuel
