Terminating Expired Subprocesos de Arbortext PE
Each time the work thread runs, it examines idle Subprocesos de Arbortext PE in its pool. If any idle Subproceso de Arbortext PE is older than the configured maxLifetime period (explained in The maxLifetime Attribute), the work thread terminates the Subproceso de Arbortext PE.
In addition, if the longest idle Subproceso de Arbortext PE has been idle longer than the configured maxIdleInterval period, the work thread terminates that one as well, provided there are more than the minimum number of Subprocesos de Arbortext PE running.
In either case, if the number of activated Subprocesos de Arbortext PE drops below the minimum configured number of Subprocesos de Arbortext PE (explained in The minSubprocesses and maxSubprocesses Attributes), the work thread starts a new Subproceso de Arbortext PE.
