Yes, you should use your userspace algorithm to tune the oom killer via the oom_adj and you can check the effect of your changes with oom_score. I posted a one liner ugly script to do that a few days ago on l-k. The oom_adj has this effect on the badness() code: /* * Adjust the score by oomkilladj. */ if (p->oomkilladj) { if (p->oomkilladj > 0) points <<= p->oomkilladj; else points >>= -(p->oomkilladj); } The biggest the points become, the more likely the task will be choosen by the oom killer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
