Will Andrews 8311a2b8a4 Add vm.panic_on_oom sysctl, which enables those who would rather panic than ... kill a process, when the system runs out of memory. Defaults to off. Usually, this is most useful when the OOM condition is due to mismanagement of memory, on a system where the applications in question don't respond well to being killed. In theory, if the system is properly managed, it shouldn't be possible to hit this condition. If it does, the panic can be more desirable for some users (since it can be a good means of finding the root cause) rather than killing the largest process and continuing on its merry way. As kib@ mentions in the differential, there is also protect(1), which uses procctl(PROC_SPROTECT) to ensure that some processes are immune. However, a panic approach is still useful in some environments. This is primarily intended as a development/debugging tool.
