that all is not applied to services started by init scripts you need the ulimit command inside a from the init script *sourced* file or use something like systemd with native settings http://superuser.com/questions/454465/make-ulimits-work-with-start-stop-daemon http://www.freedesktop.org/software/systemd/man/systemd.exec.html LimitCPU=, LimitFSIZE=, LimitDATA=, LimitSTACK=, LimitCORE=, LimitRSS=, LimitNOFILE=, LimitAS=, LimitNPROC=, LimitMEMLOCK=, LimitLOCKS=, LimitSIGPENDING=, LimitMSGQUEUE=, LimitNICE=, LimitRTPRIO=, LimitRTTIME= These settings control various resource limits for executed processes. See setrlimit(2) for details. Use the string infinity to configure no limit on a specific resource.
