They are adjustable at run time. root@laptop ~ 23:55:26 Fri Jul 13 # sysctl kern.maxfiles kern.maxfiles: 16424 root@laptop ~ 23:55:41 Fri Jul 13 # sysctl -w kern.maxfiles=18000 kern.maxfiles: 16424 -> 18000 root@laptop ~ 23:55:59 Fri Jul 13 # sysctl kern.maxfiles kern.maxfiles: 18000 To make your settings come back on reboot create /etc/sysctl.conf with: kern.maxfiles=16424 kern.maxfilesperproc=12000 Choose your own numbers for the right hand side.
