I think that DavidG wrote our clist code?? Yes, I wrote it. Bruce revamped/extended the clist reservation code, however - the reservation stuff I originally wrote was far too inadequate for the job. I haven't seen the above diagnostic for probably close to a year, and I'm surprised to see it pop up now. There haven't been any changes to the code involved in this for a long time (>6 months), so it seems likely that the problem is exposed by a change in activity on that system rather than by a code change. The diagnostic message is generally not a problem, but it does indicate a software problem that is most likely related to doing serial I/O to a port after it has been closed. ...this kind of problem generally falls into Bruce's domain.
