Ah, I knew I wasn't crazy. And no, I was not just removing storage and wondering why things crashed :). Yes, I'm now using older but useful QLA2200 cards on each node. I'm also using Brocade switches, a 2800 and 2400's without fabric zones. I'll have to peek at the logs the next time it happens, don't have any handy at this point.
