You can use sysctl ajust kernel values "kern.maxfiles"
type this in your prompt
#sysctl kern.maxfiles
kern.maxfiles: 10000 (this is your current maxfiles values)
then you can add thie values
#sysctl kern.maxfiles=15000
kern.maxfiles: 10000 -> 15000
and if you want keep this values edit /etc/sysctl.conf
add this line kern.maxfiles=15000.
next reboot will keep this values.
Sorry,My not good english.
