The maxBusyInterval Attribute
This attribute specifies the number of seconds that the Arbortext PE sub-process pool work thread (explained in Arbortext PE sub-process Pool Work Thread) will wait for an Arbortext PE sub-process response to be returned to the Arbortext PE Request Manager. The default value is 1800 seconds (30 minutes). If an Arbortext PE sub-process does not respond with a result before this interval elapses, the Arbortext PE sub-process pool assumes that the Arbortext PE sub-process 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 sub-processes 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 sub-process 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 sub-process for failing to respond.
