Deployment Automation - Importing application stuck

I was importing application from one server to another using deployment automation and it got stuck due to some reason while executing the DDL scripts. Now I am not able to import any application into the target server. It is giving the below error.
Error message: Error starting the deployment. Another deployment is already running..

I am using Linux OS and i am not able to identify the pid or process which is running in the server. If i get the pid or process id then I can forcefully kill it.
Attaching screenshots. Please suggest.
