I think you'll find I wasn't insisting on anything, although I will confess that seeing the near instantaneous flip from bug report state "open" to "feedback" accompanied by a "you debug it, end user" is a wee bit discouraging when one has already done what seemed possible. > Meanwhile, you have a developer who is willing to spend his > time, effort, and energy; free of charge; to assist you. I do appreciate that, Doug :-) I wish I had a copy of that production system so I could take advantage. From the reports I've found, this particular bug has been present in FreeBSD versions going back at least to 5.0. I've seen it myself back in 7.0 as well. The md device does not appear to me to be safe to use for file-backed memory devices. Carl / K0802647
