1. <operating system> What Unix does when a critical
internal consistency checks fails in such a way that Unix
cannot continue. The kernel attempts to print a short
message on the console and write an image of memory into the
swap area on disk. This can be analysed later using adb.
The kernel will then either wait in a tight loop until the
machine is rebooted or will initiate an automatic reboot.
Unix manual page: panic(8).
2. Action taken by software which discovers some fatal problem
which prevents it from continuing to run.
