No, kern.ipc.nmbclusters is read-only. Setting this in /etc/sysctl.conf is futile, it'll never actually be set in the kernel this way, the change will just get a read-only error, just like you would once the machine is booted. As long as I can remember it's been like this. <snip> sysctl: oid 'kern.ipc.nmbclusters' is a read only tunable sysctl: Tunable values are set in /boot/loader.conf <snip> -mpf --- Only dimly aware of a certain unease in the air --- Vulpes Velox wrote: > On Fri, 13 Feb 2004 14:20:43 -0600 > Matt Freitag <mpf@inodes.us> wrote: > > > >> For FreeBSD to support that many concurrent connections some kernel >> values must be tweaked.
