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.): ######################################################## START-TIME =26.01.2007 09:00
