This is a more reliable method that accounts for existing pidfiles, procname and interpreter settings. Current method of obtaining the pid for oomprotect="YES"|"ALL" processes in certain cases fails to find a unique pid. One such case are rc.d scripts defining command as: command="daemon" which results in all processes started via daemon being selected and passed to protect(1) which fails and prints usage: $ /etc/rc.d/exampled restart Stopping exampled. Starting exampled. usage: protect [-i] command protect [-cdi] -g pgrp | -p pid Running the same with -x reveals what happens: + pid='3051 4268 4390 4421 4427 4470 4588 4733 4740 4870 4949 4954 4979 5835 5866 55487 55583 56525 57643 57789 57882 58072 58167 99419' + /usr/bin/protect -p 3051 4268 4390 4421 4427 4470 4588 4733 4740 4870 4949 4954 4979 5835 5866 55487 55583 56525 57643 57789 57882 58072 58167 99419 usage: protect [-i] command protect [-cdi] -g pgrp | -p pid We have a more reliable way of obtaining pid already defined in rc.subr and available when protect(1) needs it. We can simply `eval $_pidcmd` which also invokes `check_process` but properly accounts for existing pidfile, procname and interpreter settings. With the change the pidfile is properly obtained.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
