The Arbortext PE Request Manager servlet terminates when the servlet container calls the method com.arbortext.e3.E3servlet.destroy. The Arbortext PE Request Manager passes the termination request to each Arbortext PE sub-process pool, and each pool sends a signal to every running Arbortext PE sub-process. Idle Arbortext PE sub-processes terminate silently. Allocated busy Arbortext PE sub-processes return an error to the calling thread in the Arbortext PE Request Manager, which is returned to the requesting client. If an Arbortext PE sub-processes is allocated but not yet busy, an error is returned immediately when it starts processing.

Each pool work thread waits for Arbortext PE sub-processes to terminate so it can delete their temporary directories. If all Arbortext PE sub-processes have not terminated before the time configured by the pool's maxShutdownInterval attribute (explained in The maxShutdownInterval Attribute), the work thread terminates, leaving some temporary storage still allocated.
