>Description:
http://www.freebsd.org/doc/faq/troubleshoot.html#PROC-TABLE-FULL
says:
"If your machine is lightly loaded, and you are simply running a very
large number of processes, you can adjust this with the kern.maxproc
sysctl.
...
To make a sysctl permanent across reboots, set this in
/etc/sysctl.conf in recent versions of FreeBSD, or /etc/rc.local in
older versions."
However, this particular tunable needs to be set in /boot/loader.conf and
requires a reboot.
It's true that attempting to make the change manually tells you this:
# sysctl kern.maxproc=2000
sysctl: oid 'kern.maxproc' is a read only tunable
sysctl: Tunable values are set in /boot/loader.conf
However, readers of this document might be inclined just to put a setting in
/etc/sysctl.conf, and then find it doesn't work.
>How-To-Repeat:
>Fix:
Refer to /boot/loader.conf, and/or cross-reference to
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/configtuning-sysctl.html
(Personally I don't know a way to tell whether sysctl variable X is a
/boot/loader.conf tunable or an /etc/sysctl.conf frob other than trying to
change it. If there's a better way, please document that too :-)
