The maxBusyInterval Attribute
Specifying maxBusyInterval sets the maximum time in seconds that an Arbortext PE 子进程 is assumed to be busy processing a request. This attribute allows Arbortext Publishing Engine to terminate an Arbortext PE 子进程 that is no longer accessible due to an error condition. The default value is 1800 seconds, or thirty minutes. Setting the value to 0 means there is no limit.
* 
It's possible that an Arbortext PE 子进程 could be terminated while it's processing a lengthy job. When you set maxBusyInterval, estimate a value that's higher than the time it would take to process the most extensive request you might submit.
