Carsten, The incomplete-ness was the result of syslogd falling over (took me a while to figure it out). It was also the reason authentication, sshd and telnet weren't working properly. I killed the syslogd process and restarted syslogd and the server is operational again...
There has been no sense (dasd) messages logged to syslog since then either... I'ld be interested to see what is causing the log entries all the same... It would be great if it was possible to decode the sense data, but it's not as urgent now...
