Maybe you shouldn't have cut off the other line from my 2-line mail ;))) The most probable reason for the stalls is the fact that page_launder (like shrink_cache) will try to write out the complete inactive list if it's almost full of dirty pages, so the system will still be stuck in __get_request_wait seconds after the first few megabytes of the paged out inactive pages have been cleaned already. cheers, Rik -- Bravely reimplemented by the knights who say "NIH". http://www.surriel.com/ http://distro.conectiva.com/ -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
