Sometimes, can't Start and Stop the DevTest components either as Services or executable's and seems the processes are in hung state.
How to handle hung processes in DevTest?
All supported DevTest environments.
You can end the DevTest hung process as below:
. In Microsoft Windows: Open the Task Manager and look for the specific DevTest process which is in hung state and "End the Task".
. In Linux/Unix..: You can use "ps -ef | grep java" command without quotes and this should provide a list of all the running DevTest processes. Get the process id of the specific service which is in hung state and delete it with "kill -9 processId" command without quotes.
