Qlik Sense Server - ticket authentication error cause the system lacked sufficient buffer space or..

Hello,

I'm facing the below error in a Qlik Sense Enterprise multinode deployment with 2 nodes.

/////
An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full 127.0.0.1:4243
at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress)
at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception)

Stack trace: at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context)
at System.Net.HttpWebRequest.GetRequestStream()
/////

This happens once a while and it causes the user ticket authentication failing.

Restarting both nodes is needed to recover.

Could someone help me to understand the root cause and to fix it ?

Many thanks in advance for your time.

Best Regards

Andrea
