I went and deleted the line and the webGui started up... I don't even remember what I was trying to do by setting that... probably did it years ago now
I think I had drive eight die, the LSI card died and one of the ports/cables in the hotswappable cage died ... migrating disks around seems to have gotten everything stable and now I'm rebuilding the failed drive and adding a second parity to help protect me as my current drives age...
Thanks for all the help!
