Cannot increase open file descriptors above 1024

[Pablo Umanzor]

try

/etc/security/limits.conf

add

freerad soft nofile   31000
freerad hard nofile   32000

i use freerad because this user launch freeradius daemon, it depends who is
the owner (could be sometimes root but not recomend)

you can check with this command

ulimii -a

if the number open files it changed

also reboot the box if the previous step  it doesn't work

Best Regards
Pablo Umanzor
