You can try putting: options NMBCLUSTERS=16000 in you Kernel Config, and then recompling, and then adding: kern.maxfiles=32768 kern.maxfilesperproc=32768 into your /etc/sysctl.conf; or do: sysctl -w kern.maxfiles=32768 sysctl -w kern.maxfilesperproc=32768 So that you dont have to reboot again; both will work, but the second method you have to do every single time you startup your computer.
