Darwin-dev mailing list (Darwin-dev@lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.appl... sorry to disturb again, but the machine I am debugging cannot be left off-line too long as it is a production server (and is at a remote location), so I am looking for some advice. PowerMacG4 DP400 10.4.8 + security update 007 + ACARD 6890M SATA RAID configured for mirroring. Symptoms: every few days the machine hangs (it looks like the old "rainbow of death") remaining responsive to pings but otherwise inaccessible from both the console and ssh. Even telnet to an open tcp port (say 80) will establish the connection but the process on the other side will not respond any further (in this example a GET / HTTP/1.0 <cr> <cr> will not give anything). I have two prime suspects: the ACARD (driver or card) and lookupd. The ACARD is suspect because this is the only machine running 10.4.8 I have mounting this card and the only one suffering from these hangs. lookupd is suspect simply because the symptoms are so similar to what one would get when lookupd stops working. I would try to rule out lookupd. Maybe have it log the most verbose (but it'll spam syslog too unless you block it) and log it to a separate file, to examine after a hang. man lookupd will show the way. Also, you could kill and restart lookupd maybe every 24 hours or so. That might be enough to keep it alive, if indeed it is lookupd dying. Those are some troubleshooting methods I would use.
