Situation
Ich hatte über mehrere Monate regelmässig bei meinem Hewlett-Packard Server eine Kernel Panic. Zu beginn habe ich diese alle paar Tage erhalten, meistens um 1 Uhr nachts wenn mein Rsync Skript meine Daten auf einen externen Server kopiert hat. Nachdem ich dieses Skript nicht mehr ausgeführt habe, traten die Kernel Panics nicht mehr auf. Ich habe dann ein Skript erstellt, was meine Dateien in gleich grosse Archive packt. Dieser Vorgang erhörte die Systemauslastung extrem, was für einen Server im Normalfall zu keinen Problem führen sollte. Auf meinem System sah das allerdings ganz anders aus, ich habe dann jede Nacht zwischen 1 und 3 Uhr eine Kernel Panic erhalten.
Da ich in der ILO Konsole nur eine Auflösung von 640x480 Pixel habe und die Kernel Panic Logs sehr lang werden können, musste ich eine Lösung suchen diese auslesen zu können. Da bei meinen Kernel Panic\'s nicht mehr auf die Festplatten und Netzwerkschnittstellen zugegriffen werden konnte, habe ich die komplette Ausgabe des Systems über die RS232 (ttyS0) Schnittstelle des Servers ausgegeben. Mit einem Nullmodem-Kabel habe ich diese an einem anderen Server wieder eingelesen (
