Have you seen the OOM killer policy implemented in memory the resource controller? http://kernelnewbies.org/Linux_2_6_25#head-450b26e12955b8035a05cf07b3f31c501ee4bfab BTW read the TODO comment in this commit log... ;-) http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=c7ba5c9e8176704bfac0729875fa62798037584d Maybe a possible solution could be to just run critical and non-critical applications in 2 different cgroups, using different memory policies. Anyway, userspace OOM handling would surely permit to implement more interesting features. -Andrea -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
