 Hi,

 I am using the akka http scaladsl library to do a HTTP calls against a 
 server. I am running a test where I have 15 threads running concurrently 
 each making around 250 GET calls(15*250). Trying to run this test for 
 three 
 hours but I see that after two and half hours of execution I could see
 Detail: akka.stream.StreamTcpException: Connection failed. exception 
 being thrown.

 Initially I thought the servers isn't accepting the incoming requests. 
 But, ran the same test directly against the server and could see no issues.
 Code snippet to connect to the server -

 connectionFlow= 
 Http(context.system).outgoingConnectionTls(req.uri.authority.host.address(),
  
 port)
 Source.single(req.withUri(req.uri.toRelative)).via(connectionFlow).runWith(Sink.head)
  
 - Here, req is the HttpRequest.

 Could someone please help me out why is that StreamTcpException 
 exception is thrown?

Hi Johannes,

I tried with Http.SingleRequest as suggested but could see the following 
exception

akka.stream.BufferOverflowException: Exceeded configured max-open-requests 
value of [32]

This time the test has lasted only for 40 odd minutes(as compared to 
previous test result which lasted for over 2hrs 30mins.). Could you please 
let me know what configuration changes should be made?

2017-02-27 Thread 'Johannes Rudolph' via Akka User List 
Hello,

the error is thrown 
here: 
https://github.com/akka/akka/blob/master/akka-stream/src/main/scala/akka/stream/impl/io/TcpStages.scala#L303.
 
I agree it's hard to see why that error would happen. One thing that could 
have happened is that a connection attempt was very slow and so the 
idle-timeout kicked in and killed the TCP stage before a connection was 
established. Either there was a real connection problem, or the 
infrastructure didn't make progress in due time e.g. because of a thread 
starvation issue.

Btw. using `Source.single().via(connectionFlow).runWith(Sink.head)` is 
discouraged. Please use `Http.singleRequest` instead. See also the note 
at 
http://doc.akka.io/docs/akka-http/current/scala/http/client-side/host-level.html#host-level-api.
