title: What happens when WebContainer thread pool (WebSphere) is fully used and new request is received?
body: <p>Got question about WebSphere and cannot find anything in the documentation...</p>
  
  <p>What happens when WebContainer thread pool is fully used and new request is received? I am talking about the situation when all are used and we reached max thread pool size meaning that new one may not be created to process the request.</p>
  
  <p>Will the request:
  - fail immediately and the response will contain some kind of error?
  - WAS will somehow "queue" the request for given period and process it when one of the threads is back in the pool? Some kind of error/timeout may still happen if the wait time is too long?
  - WAS will "queue" the request indefinitely and the timeout might only happen on the User side (web browser/app)? </p>
