In this scenario, we have Team Foundation Server (TFS) integrated with CA Release Automation(RA) via RA TFS plugin. We have created a pool of agents for TFS and when we deploy a release in TFS using the CA Release Automation plugin, it ends up on a disabled TFS agent.
Result: the 'Deploy' step keeps on running with "agent: not allocated". Please see screenshot below where a build is set to a stage "Agent: not allocated" and hence never proceed.

During our analysis we found below information in relation to TFS
To overcome this scenario below is recommended.
