PoolMgr rejection retries exhausted

   

A client component has reached its maximum number of retries to get a worker from the Pool Manager. Whenever the Pool Manager has no available workers, it rejects the client's request for a worker. The client then waits for some time and retries the request. This cycle continues until the Pool Manager has a worker to assign to the client or the client reaches its maximum number of retries, whichever comes first.

Try increasing the number of workers.
