--- Comment #1 from Diego Casati <diego.casati at gmail.com> ---
Rather an old ticket but I thought it was worth going over it. 

As of FreeBSD 10.0, somaxconn has been replaced by soacceptqueue as stated at
the HISTORY section of listen(2):

HISTORY
     The listen() system call appeared in 4.2BSD.  The ability to configure
     the maximum backlog at run-time, and to use a negative backlog to request
     the maximum allowable value, was introduced in FreeBSD 2.2.  The
     kern.ipc.somaxconn sysctl(3) has been replaced with
     kern.ipc.soacceptqueue in FreeBSD 10.0 to prevent confusion about its
     actual functionality.  The original sysctl(3) kern.ipc.somaxconn is still
     available but hidden from a sysctl(3) -a output so that existing
     applications and scripts continue to work.

The handbook section has also been updated. 

thanks,
