2nd SubscribeDataChange calls freeze was created by phil56

Hi,
I'm evaluating the QuickOPCUA .NET solution (2017.2)

I'm testing the subscription part.

My code :

EasyUAClient client = new EasyUAClient();
 
UAEndpointDescriptor endPointDescription = new UAEndpointDescriptor("opc.tcp://localhost:51210/UA/SampleServer");
endPointDescription.UserIdentity.UserNameTokenInfo.UserName = "user";
endPointDescription.UserIdentity.UserNameTokenInfo.Password = "password";
 
client.DataChangeNotification += Client_DataChangeNotification;
 
client.SubscribeDataChange(endPointDescription,"ns=2;i=10221", 500);
//Thread.Sleep(100);
client.SubscribeDataChange(endPointDescription,"ns=2;i=10216", 500);

The first SubscribeDataChange works well, but if I add a second one, the program freezes
on the 2nd SubscribeDataChang

(I don't want to use the SubscribeMultiple method)

If I add the Thread.Sleep (100) between the two SubscribeDataChange calls, everything is ok.

Any hints on what could be the issue ?

Thanks in advance

Regards.
