Something is weird with the deployed objects, platform specifically. You can look at the registry entry for PlatformNodes, and see what it has for Platform 4 and 3. Somewhere, between the nodes, there is a mismatch. It could be that one did not get an update, or something is stuck. One sure way to cure.... Undeploy everything, delete the PlatformNodes folder in the registry for all of the nodes in your system, then deploy the galaxy and all platforms/objects again. If you open a support ticket and work with an engineer, you might be able to find it without the full undeploy.
There is a mismatch in the information in the PlatformNodes registry key. This is uncommon, but here are some possible causes:
An orphaned node that is currently up and running, disrupting platform-to-platform communications.
A problem with global data cache distribution that prevented PlatformNodes from being synchronized across all nodes in the galaxy.
DNS/network issues that caused the machine name to get resolved to an incorrect IP address.
Other issues.
Here are some steps you can perform to narrow down the issue:
On the node where the warning is logged (Node A), launch regedit and navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ArchestrA\Framework\Platform\PlatformNodes\Platform4, and get the “Machine” value. It contains the name/address of platform 4 (Node B).
Ping the address of the target machine and see what IP address it resolves to. Is the IP address what you expect? If not, check your DNS/network. If yes, continue with next steps.
Go to the machine identified in the previous steps (Node B).
Determine if you expect to have a platform running on this node. If yes, continue with the next steps.
On Node B, launch regedit and navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ArchestrA\Framework\Platform\PlatformNodes\Platform0 and check the Id entry. Based on the warning message, it should show 3.
Go to your Galaxy repository machine. Launch OCMC -> Platform Manager. Find the platform with “Node Name” equal to “Node B“. What is the “Platform ID” for that entry? Is it 3 or 4? If the “Platform ID” is 4, then redeploy “Node B”. If the "Platform ID" is 3, redeploy “Node A”.
