No, we have a half-dozen servers running 2.2.2 and 2940s and they *all* have this problem. These servers were built over a period of a year, so it's not a "bad batch" of controllers, either. The thing that consistently flips them out is a tape write error, although they regularly do it when NO tape i/o is happening. As someone noted earlier, the SCSI code is not very tolerant of errors and is being completely rewritten. The situation can be summarized: - The problem is real, it's not imaginary - It's widespread and common - It's in FBSD - It's being (hopefully) fixed Until then, all we can do is live with it and hope that a future release will let me go back to sleeping easily :) Cliff
