Sorry it has been a long time and very busy so i have not checked back here.
At the time i got the error i knew basics of webMethods but now few courses later, things look brighter.
The issue was cause by mismatch between the WmDeployerResource package, and the WmDeployer.
To resolve it, i had to redeploy the resource package again to the node.
Login to the IS admin console and go to :
wm 8.2+ - “Solutions>WmDeployer”
wm 9+ - “Solutions>Deployer”
Under “Servers>IS & TN” Select the check box infront of the node name giving you the error, and then click “Install”.
This will redeploy the resource package.
Please let me know if this solved your problem.
PS: this happened after a WmDeployer fix was applied on the server, so the lesson-learned is, after fix insulation on the WmDeployer package, the deployer resource must be redeployed to all nodes.
