I would like to know the % of orphans other pools have, because I still have the feeling that this pool has a fairly high ratio.
This most recent orphan was caused by a bitcoind issue that an emergency patch was supplied for. The issue caused the bitcoin daemon that the pool daemon was hidden behind to crash due to OOM and the pool daemon no longer received updates. It's unfortunate but not much could be done about bitcoind bugs.
This one, or are we talking about another one?

Why in your GUI can we not get access to the orphaned data(block number)?
