Not the biggest deal, but thumbs from Special:VipsTest sometimes fail. Not sure what's going on, but perhaps one of the back-end servers has that cgroup issue. Reloading a bunch of times tends to fix things, eventually the thumb succeeds and it gets cached. Thumbnailing doesn't go through normal thumb.php, so no idea what the host name is that is bad.
