I may be missing something obvious, but I've got a couple Red Hat EL4 servers running FDS 1.0.2, and I keep getting the dreaded "Not listening for new connections - too many fds open" error. I've looked at all the install and how-to guides, and have the following set up: /etc/security/limits.conf: * soft nofile 104851 * hard nofile 104851 /etc/sysctl.conf: fs.file-max = 131072 /etc/profile: ulimit -n 131072 /etc/pam.d/login: session required /lib/security/pam_limits.so Still, as soon as FDS hits 1024 FDs open, everything blows up. What have I missed? I've also added a "ulimit -n 131072" to the top of the server's init script, but no dice.
