## 7.6. Cluster job failure: Multiple NIC card issue

The cluster submit host uses multiple Network Interface Cards (NICs). The servo process that is launched on the cluster submit host is obtaining an IP address with which EKM cannot communicate. An error similar to the following may appear in the EKM server log:

    TcpClient createSocket attempt 1 failed for host: 10.10.10.1, port: 51772

Solution: Specify an `EKM_SERVO_IP_ADDRESS` environment variable on the cluster submit host. Refer to Dealing with Multiple Network Interface Cards (NICs) in the Administration Guide.
