I agree that it shouldn't deadlock (worst case swapping to a file on zfs should be disallowed), but is there a particular reason you created a file on ZFS rather than creating a zvol to swap to? ISTM that creating a volume would result in better performance than a file and I can't see any downside to it. Craig
