This looks like pointers to files that were already deleted/purged. I
once faced this errors but that was on bad controller, I don't think
this can be caused by bad memory/errors. When that happened I scrubbed
pool, removed all files noted, cleaned zpool errors (they are
persistent, even the file was removed and snapshots doen't exist they
are still shown) and scrubbed the pool again.
