Hello Support,

I'm running the platform(2.43.2) and API(2.12.6) release.
When I try to login with multiple threads, then sometimes these related exceptions occur:

java.io.IOException: Client not online
   at com.dukascopy.dds4.transport.client.TransportClient.controlRequest(TransportClient.java:557)
   at com.dukascopy.dds4.transport.client.TransportClient.controlRequest(TransportClient.java:455)
   at com.dukascopy.dds4.transport.client.TransportClient.controlRequest(TransportClient.java:517)
   at com.dukascopy.api.impl.connect.DCClientImpl.connectedInit(DCClientImpl.java:700)
   at com.dukascopy.api.impl.connect.DCClientImpl.authorized(DCClientImpl.java:990)
   at com.dukascopy.dds4.transport.client.events.AuthorizedEvent.execute(AuthorizedEvent.java:23)

   at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603)
   at java.lang.Thread.run(Thread.java:722)

After that there is always this:

java.io.IOException: Client not online
   at com.dukascopy.dds4.transport.client.TransportClient.controlRequest(TransportClient.java:557)
   at com.dukascopy.dds4.transport.client.TransportClient.controlRequest(TransportClient.java:455)

   at com.dukascopy.api.impl.connect.DCClientImpl$11.run(DCClientImpl.java:1204)
   at java.security.AccessController.doPrivileged(Native Method)

   at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603)
   at java.lang.Thread.run(Thread.java:722)

Again, these exceptions occur at random, I would guess 1 out of 5.
See also these bug reports, which are also related:
Bug1
Bug2
All together it seems that the startup process/synchronization is very unstable at the moment.

Thanks for fixing this.

Hello FXjuxe!

Standalone API does not provide ability to maintain multiple simultaneous logins from one application. Multiple threads won't help as ClientFactory.getDefaultInstance() always returns the same object.

Hello Support,

thanks for the hint, the error was on my side with multiple API jars in one folder
If its OK for you I will delete this post.

Regards,
Juergen
