--- Comment #1 from Fabian Keil <fk@fabiankeil.de> ---
At least on vanilla FreeBSD kern.ipc.soacceptqueue merely specifies an upper
limit,
it does not prevent the application from requesting a smaller one.

Many applications use a hardcoded value like 128 without checking
if a higher value would work.

For details see the "listen" and "getsockopt" man pages.
