A word about bad traps


A computer system will also crash if it detects a condition in the hardware that should not happen. On UNIX systems, this type of crash is referred to as a "bad trap." From the system administrators' point of view, bad traps and software panics are handled in the same way.

UNIX systems perform millions of traps each day, so please don't panic when you hear the word trap. However, on rare occasion, you may encounter a bad trap. When your UNIX system sees that, it will invoke panic() .

Later on, in great detail, we will explore traps; both the expected good traps that occur on your system all day long and the unexpected, unwelcome bad traps.
