This makes it very hard to debug the problem. The machine has 512MB of RAM as you can see. The console output is: .... Checking for core dump: dumplo = 537526272 (1049856 * 512) savecore: reboot after panic: page fault Jan 21 12:30:06 localhost savecore: reboot after panic: page fault savecore: system went down at Wed Jan 21 12:23:45 2004 savecore: writing compressed core to /usr/crash/vmcore.16.gz savecore: /usr/crash/vmcore.16.gz: Illegal seek Jan 21 12:30:06 localhost savecore: /usr/crash/vmcore.16.gz: Illegal seek savecore: WARNING: vmcore may be incomplete ....
