I have been considering it a minor issue. But then, I also hoped
that someone would notice the new warning message from `ac', rerun
it in debug-mode, and be able to match up the bad-records with
whatever they were doing at the time. And then we'd have a good
clue as to which program is sometimes writing these bad records.
But I guess that in normal operation, people won't see that message
until the monthly-run, so maybe it won't come up often.
In the cases I saw, it was just a few bad records over the course
of a month, so I assume that whatever-it-is, it is something that
doesn't happen often. I haven't seen it happen on my systems at
all, but then almost all my sessions are made via ssh, so in my
case it would either happen all the time, or it would probably
never come up.
