Which kernel precisely? What does "vmstat 1" look like? If you swapoff/swapon between application runs does the effect persist? What does the application do? What does /proc/sys/fs/inode-nr contain? This does not sound like a result of the swap caching behaviour. Once you start swapping that memory _is_ returned (or something is not working as it should). --Stephen -- To unsubscribe, send a message with 'unsubscribe linux-mm my@address' in the body to majordomo@kvack.org.
