Process Termination
There are many reasons for process termination:
- Batch job issues halt instruction
- User logs off
- Process executes a service request to terminate
- Error and fault conditions
- Normal completion
- Time limit exceeded
- Memory unavailable
- Bounds violation; for example: attempted access of (non-existent) 11th element of a 10-element array
- Protection error; for example: attempted write to read-only file
- Arithmetic error; for example: attempted division by zero
- Time overrun; for example: process waited longer than a specified maximum for an event
- I/O failure
- Invalid instruction; for example: when a process tries to execute data (text)
- Privileged instruction
- Data misuse
- Operating system intervention; for example: to resolve a deadlock
- Parent terminates so child processes terminate (cascading termination)
- Parent request
- Fatal error

Famous quotes containing the words process and/or termination:
“In contrast to revenge, which is the natural, automatic reaction to transgression and which, because of the irreversibility of the action process can be expected and even calculated, the act of forgiving can never be predicted; it is the only reaction that acts in an unexpected way and thus retains, though being a reaction, something of the original character of action.”
—Hannah Arendt (1906–1975)
“We hoped for a happy termination of this terrible war long before this; but God knows best, and has ruled otherwise.”
—Abraham Lincoln (1809–1865)
