It's not too bad since the data can be reclaimed easily. The problem in your case is that the dentry and inode cache didn't get reclaimed. Maybe there is a leak so they can't get reclaimed at all or maybe they just don't get reclaimed fast enough. I'm looking into the "can't be reclaimed fast enough" problem right now. First on 2.4-rmap, but if it works I'll forward-port the thing to 2.5 soon (before Linus returns from holidays). regards, Rik -- Bravely reimplemented by the knights who say "NIH". http://www.surriel.com/ http://distro.conectiva.com/ Current spamtrap: october@surriel.com -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
