Arbortext PE sub-process Pool Work Thread
Each Arbortext PE sub-process pool starts a background work thread that runs periodically and attempts to perform routine maintenance. The interval between runs is configured in the workThreadInterval attribute of each SubprocessPool element in e3config.xml. The default is every 5 seconds. Each time it runs, a work thread checks for the following items. Descriptions of each item follows.
• unusable Arbortext PE sub-processes
• Arbortext PE sub-processes that should be terminated
• Arbortext PE sub-processes that have exceeded the allowed idle or lifetime period
• deferred requests to delete directories
• whether a new Arbortext PE sub-process should be started
