Sorry about posting to @current.
Yep, kern.ipc.semmap does exists on FreeBSD 8.2 (I have configured it on
sysctl.conf) but on FreeBSD 9.0 its gone, Volodymyr Kostyrko pointed out
that this options need to be configured now on /boot/loader.conf (file
that
on 9.0 I had to create it manually unlike 8.2).
Where can I find this type of changes that were made on 9.0?.
Thank you.
http://www.freebsd.org/releases/9.0R/relnotes-detailed.html should
have all changes in it; this seems to have been missed.
This is the change:
r224016 | bz | 2011-07-14 14:18:14 +0000 (Thu, 14 Jul 2011) | 10 lines
Remove semaphore map entry count "semmap" field and its tuning
option that is highly recommended to be adjusted in too much
documentation while doing nothing in FreeBSD since r2729 (rev 1.1).
ipcs(1) needs to be recompiled as it is accessing _KERNEL private
variables.

which suggests that the option has not done anything for a very long time.
Cheers
Tom
