Here are some areas to look at when troubleshooting the Cluster Manager.

Inconsistent Frame Rate

The cluster manager updates its views periodically. During updates, there may be a drop in the frame rate. Close the cluster manager to stop updates and restore the frame rate.

Unable to Connect to a Server

• Use a ping command, from a windows command shell, to see if the server is reachable.
• Determine if the VREDClusterService is running on your machine.
• Check your firewall settings. The cluster manager uses port 8889.
• Try to stop the VREDClusterService and start it from a windows command shell. Go to the bin/WIN64 folder of the VRED installation and call VREDClusterService -e -c. Check the console for error messages.

Unable to Render on a Cluster Queue

• Check that there are render nodes booked for the cluster queue.
• Check that you have an extra VREDPro license for the queue host PC.
• Check that the queue is not paused.

Unable to Render Substance Variant States on a Cluster Queue

If Substance variant states in the Render Jobs of the Render Queue are not rendered correctly with the Cluster Manager, look at the Queue Host in the Cluster Manager configuration. Is the Cluster Queue Host running on Linux? If so, this is because the Substance engine is not available on Linux.

If you can run the Cluster Queue Host on Windows, do this, as it will resolve the issue.
