The fact that it doesn't happen on a single processor makes me believe it's still a problem with the quicklists not getting freed properly. It would be nice if someone could go in with system tap or just plain "gdb vmlinux /proc/kcore" and verify if there is a large number of pages queued up on the quicklists on some of the CPUs, while at least one of them is zero. (It would be nice to have quicklist statistics exported somewhere, too.) -hpa -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
