We just have a pool for atomic allocation it may not be large enough for the increased pressure on the regular pages. echo 1000 2000 4000 >/proc/sys/vm/freepages This way you'll basically waste 16mbyte of ram. It's just to check if the ATOMIC allocation shortage is the source of the segfault or not. -- Andrea -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
