RE: Best Way to Kill Runaway Interactive Jobs?

We had that happen when a user closes their terminal session and the
interactive program continuously tries to write to the screen.  Since the
screen is not there anymore, the write fails, the error indicator comes on.
In this program, the programmer has studiously ignored the error indicator
and continued to process in the program, eventually coming back around to
the write statement.  Hence an infinite loop that consumed major portions of
the processor.

You might want to look at the system values that relate to inactive jobs -
there are a number of options there, like disconnect, end, send messages,
etc.
