I also stated it was ONLY Google Images and only if it can't fine ANY covers, so the problem lies there somewhere.

I wonder if its something competing for network resources - P2P, RSS feeds, stock tickers etc - that said I run those sort of things all day, whilst I don't use Calibres metadata & cover downloads much I've not had errors of this sort.

I'd try running Calibre on as close to a bare bones system as is possible.

I've also said I've run this before with some Amazon MOBIs and the Google Images plugin was just fine. It's choking on some EPUBS with no real internet presence, like those from Smashwords or Kobo.
