Exception while connecting to the head node RRS feed

  • Question

  • Dear all,

    We are using Windows HPC 2016 in our project. We are using developers laptops (workstations) as computational nodes. However, while connecting these nodes to the head node we are getting following exception:

    "Unable to connect to the head node"

    "The connection to the management service failed. detail error:

    System.InsufficientMemoryException: Insufficient winsock resources available to complete the socket connection initiation. --> System.Net.Sockets.SocketException: An operation on a socket could not be performed because the system lacked...."

    What could cause this issue? 

    our HPC head node configuration is 4 cores, 16GB, and Windows 2016.
