Rest server (Play Framework) gets “Read Timed out” exception during load test

问题

We are running a heavy load test (jmeter: 350 threads, 35M total requests) on a rest server using Play Framework and run into the following error after ~2 hour. We remove other components so that request simply take requests and do nothing. Anyone has any idea or simply Play Framework cannot handle heavy load like this?

Part of the application.conf : ....

db.pool.timeout=100000

play {
  akka {
    akka.loggers = ["akka.event.Logging$DefaultLogger", "akka.event.slf4j.Slf4jLogger"]
    loglevel = WARNING
    actor {
      default-dispatcher = {
        fork-join-executor {
          parallelism-factor = 64
          parallelism-max = 1000
        }
      }
    }
  }
}

There a many things to check:

Are you running Test from same machine ? if yes it's a problem
Is your machine TCP stack tuned ?
What is your JVM configuration regarding Xmx as long as your machine memory, CPU ...
What does your test look like ? could you show a screenshot with all elements unfolded ?

I think Play/AKKA can handle this load without problem so I would look into configuration issues.
