A small point but, with use of the `mark' facility in syslog, and proper
monitoring for it, you can and should be able to detect syslogd either
dying or refusing to write to files (amounts to the same thing). No news
is NOT good news, but knowing that we can key on it.

This is not intended to say that what you found is not a bug, just that
there is a way to detect it.

cheers, kinch
