Hello,
I try to limit the number of file descriptors using the variable "LimitNOFILE" inside the following systemd unit: [Unit] Description=HAProxy Load Balancer After=network.target [Service] ExecStartPre=/usr/local/sbin/haproxy -f /etc/haproxy/haproxy.cfg -c -q ExecStart=/usr/local/sbin/haproxy-systemd-wrapper -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid ExecReload=/bin/kill -USR2 $MAINPID KillMode=mixed Restart=always LimitNOFILE=5 # For testing only... [Install] WantedBy=multi-user.target But it only works for the first process spawned, wich is haproxy-systemd-wrapper: root 4421 0.0 0.1 17084 1508 ? Ss 10:11 0:00 /usr/local/sbin/haproxy-systemd-wrapper -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid nobody 4423 0.0 0.4 30104 4436 ? S 10:11 0:00 \_ /usr/local/sbin/haproxy -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid -Ds nobody 4424 0.0 0.2 30104 2508 ? Ss 10:11 0:00 \_ /usr/local/sbin/haproxy -f /etc/haproxy/haproxy.cfg -p /run/haproxy.pid -Ds # cat /proc/4421/limits Limit Soft Limit Hard Limit Units Max open files 5 5 files # cat /proc/4423/limits Limit Soft Limit Hard Limit Units Max open files 64013 64013 files # cat /proc/4424/limits Limit Soft Limit Hard Limit Units Max open files 64013 64013 files The process who listen in the socket is the last one, 4424, with the bad settings: # netstat -ntap | grep haproxy tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 4424/haproxy tcp 0 0 0.0.0.0:8088 0.0.0.0:* LISTEN 4424/haproxy haproxy-systemd-wrapper would not have to pass these values? Is it possible to pass the limits from systemd to the listening haproxy process? Thanks,
