This caused various other system services to become seriously broken, of course. When I started another copy of syslogd the problem went away. Unfortunately I don't seem to be able to get much debugging info. I can't make the syslogd process dump core because the default ulimit is not to. I can't even get a meaningful stack backtrace because the daemon is stripped. There wasn't anything useful anywhere in /var/log or on the console. If it is impossible to diagnose this problem with the information I give here then please consider this bug report to concern the lack of suitable means for diagnosing and fixing intermittent problems with system daemons (of which the syslogd is merely one example). This may be a policy problem, eg, the default ulimit being bad.
