public class AgentWorkerThreadPool
extends ServerThreadPool

This ThreadPool is used to execute async agents which put CPU load on the server. This pool is limited because NOT too many agents of this type should run in parallel. If more agents than the core-pool size want to run they are just queued. If the queue is full, more threads are started until the max-pool size is reached. Any further agent will be rejected by receiving a ServerTooBusyException.
