Monitor Knowledgebase

Summary

This monitor tracks the ability of a node to connect to the job scheduler port on the head node by using TCP/IP. If a node cannot connect to the job scheduler port on the head node, the node cannot communicate with the job scheduler to run jobs. A node attempts to connect to the job scheduler port on the head node using TCP/IP every 15 minutes by default.

Causes

This error can be caused by any of the following:

  • A problem with the HPC Job Scheduler Service on the head node

  • A problem with the firewall configuration or rules on the head node

Resolutions

  • Restart the HPC Job Scheduler Service on the head node.

  • On the head node, check the firewall settings using HPC Cluster Manager (in Configuration, click Network) or use the following HPC PowerShell command: Get-HpcNetworkInterface | Format-List

  • On the head node, check the configuration of the inbound firewall rules for the HPC Job Scheduler Service to ensure that ports required for communication with the nodes are open.
