My SCO Unix machine had a panic. How do I find out why?

There are a number of situations which can cause panics. First off, write down the actual panic message displayed on the screen when the machine crashed. Also, write down the values of CS and EIP from the register dump.

Next, reboot the system into single-user mode and run the following command to produce a panic report:

echo panic -w /tmp/panic.out | crash -d /dev/swap

This produces a report in the file /tmp/panic.out. With the original panic message and this report, someone may be able to help you; without this information, it's just about impossible to say what went wrong. In particular the section of the report listing the kernel stack may be useful in diagnosing what caused the panic.
