I am using CALDERA OPENLINUX 3.1.1 with latest patches and Samba 2.2.5 on it.
But recently I start to receive linux error "kernel: VFS MAX FILES
REACHED"
and Samba error "Too many open files". After it I tuning linux
increase open
files descriptors in
/etc/security/limits.conf
* soft nproc 4094
* hard nproc 16384
* soft nofile 12000
* hard nofile 16000
, /etc/rc.d/init.d/samba ulimit -n 12000 before start smbd, /etc/sysctl.conf
fs.file-max = 12000
And start monitoring through lsof, smbstatus every 15 min.
In a few days situation with halt limits repeat and monitiring to show (I do
not show full logs because it's very big. Only sessions which lead to
Errors.):

And how can I admin this process, restrict or limit open files in one session?
May be you have any other method or advice.
