The maxIdleInterval Attribute
Specifying maxIdleInterval sets the maximum time in seconds Arbortext Publishing Engine allows an Arbortext PE sub-process to be idle. If an Arbortext PE sub-process is idle for the specified time, it's terminated.
The maxIdleInterval value only applies if maxSubprocesses is greater than minSubprocesses and there are more Arbortext PE sub-processes running than the number specified by minSubprocesses.
