The maxShutdownInterval Attribute
Specifying maxShutdownInterval sets the maximum number of seconds that Arbortext Publishing Engine will wait to allow an Arbortext PE sub-process to shut down on its own. If an Arbortext PE sub-process has been instructed to shut down by the Arbortext PE Request Manager and it's still running after this period of time, it will be terminated.
