If I've understood it right from the mailing lists, ZFS returns memory=20 back to the OS from caches somewhat lazily, so in times of high memory=20 load ZFS system can cause some swapping. Of course, once the situation with memory load is over, swap will=20 still continue to show the max amount swapped ever, even if everything=20 is again back in real memory. So nothing to worry about I'd say. -Reko=20
