tn.query.timeout
Duration for which a query created using the doQuery API must run. If this value is relatively small compared to the time required for a long running query to complete, the query fails.
Trading Networks uses this property for all queries you perform from My webMethods (for example, queries for documents, tasks, and activity logs). In addition, this is the default for queries that you perform using the built-in services in the wm.tn.query folder.
This value must be fine-tuned based on the complexity of the query. If this value is not set, there is a possibility for the hosting Integration Server to become unresponsive for queries that run for a long duration of time.
The default value is zero seconds which means there is no timeout.
