Sandeep , i would suggest this
- option1- Go to the deployment box and restart the release agent
- option 2 - Try debugging the agent , by running the agent in debug mode In Windows Services, stop the Microsoft Deployment Agent Service Run the DeploymentAgent.exe located in %Program Files(x86)%\ Microsoft Visual studio 12.0\Release Management\bin with “debug” option from command line. (DeploymentAgent.exe debug start)
Running the agent in debug mode solved my problem.
