Yes - because now and then (about once a month) with 3.10 or so + and encrypted swap my box with 16GB RAM gets into a weird 'slow swapping' state and only swapoff/swapon gets it back to sanity. In those cases (and in general) swapoff can take half an hour to run. There is a reproducer for the swap hang at https://bugzilla.kernel.org/show_bug.cgi?id=62321 The case I see in normal use (gimp of 1200dpi+ A3 images) hits a crawl not a hang and does recover but only if you swapoff/swapon again Alan -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
