Specifying maxIdleInterval sets the maximum time in seconds Arbortext Publishing Engine allows an Arbortext PE サブプロセス to be idle. If an Arbortext PE サブプロセス 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 サブプロセス running than the number specified by minSubprocesses.
