Yes, it seems it's back online. What was wrong?

<apergos> the three hosts that were a bit spikey, I restarted lucene on them just in case but I think it probably didn't make any difference, they weren't in a hung state

So the short answer is, no idea. Those hosts already looked good in ganglia by the time I got to them.
