The maxBusyInterval Attribute
This attribute specifies the number of seconds that the Arbortext PE 子进程 pool work thread (explained in Arbortext PE 子进程 Pool Work Thread) will wait for an Arbortext PE 子进程 response to be returned to the Arbortext PE Request Manager. The default value is 1800 seconds (30 minutes). If an Arbortext PE 子进程 does not respond with a result before this interval elapses, the Arbortext PE 子进程 pool assumes that the Arbortext PE 子进程 is not usable and terminates it. An error will be returned that is usually transmitted to the HTTP client making the request.
If processing a request could take a significant amount of time, increase the value accordingly to be sure the Arbortext PE 子进程 can produce the result in the allotted time. For example, formatting a large document or one with many graphics could take a long time, and if the wait period elapses, the Arbortext PE 子进程 could terminate before it finishes formatting and publishing the document.
If you want to disable the wait process because you know processing requests will take a very long time, you can set this attribute to zero. In this case, the work thread will never terminate an Arbortext PE 子进程 for failing to respond.
