Hi All,
I just upgrade Nginx from 1.8 o 1.9 on my FreeBSD box.

Did I miss anything in the configuration? or for a busy server, it's

to use accept_mutex instead of reuseport?

In FreeBSD the SO_REUSEPORT option has completely different behavior
and shouldn't be enabled in nginx.
Should the configruation option then be disabled or silently ignored in
FreeBSD at this time?
It would be difficult to selectively ignore operating systems based on
how this function is supported. Especially if that support changes over
time.
I believe that DragonFly BSD for example supported the method most BSDs
use originally.
In the FreeBSD pattern it is designed to bleed off connections to one
service as another comes up. Such as a binary upgrade. The last socket
listener always gets new connections. This is almost the exact opposite
of what Linux does with the option (DragonFly is somewhere in the
middle). I'm personally not a BSD expert so can't say which other BSD
operating systems use the same method as FreeBSD and even which ones do
not even have a SO_REUSEPORT option.
Documentation is probably the best option for now and we have tried to
make it clear which operating systems do support this feature.
Kind Regards
