Linux: OOM Killer As Compile Time Option
Posted by jeremy on Monday, December 8, 2003 - 20:48

The recent release of the 2.4.23 kernel [story] saw the complete removal of the OOM (Out Of Memory) killer [story]. Though the current solution seems technically superior, preventing potential deadlocks during out of memory conditions, many users have requested that the OOM killer be made available as an option. 2.4 maintainer Marcelo Tosatti recently posted a small patch that provides exactly this, the OOM killer as a compile-time option. The new compile option, CONFIG_OOM_KILLER, includes the following help text:

"This option selects the kernel behaviour during total out of memory condition. The default behaviour is to, as soon as no freeable memory and no swap space are available, kill the task which tries to allocate memory. The default behaviour is very reliable. If you select this option, as soon as no freeable memory is available, the kernel will try to select the 'best' task to be killed."
Earlier in the same thread, Andrea Arcangeli suggested that users running stable servers will find the current VM much preferable, however some desktop users may prefer to use the OOM killer. It is very likely that this patch, or something like it, will soon be merged into the 2.4 stable kernel.
