Server port in use when you are restarting the development environment
If the product crashes or the Java™ product process is stopped externally, such as in the Windows Task Manager, while the server is running, you might receive a Server port port_number is in use message when you try to start the server after you restart the development environment. Some server resources are not fully released.
Important: Applicable to WebSphere®
Application Server traditional
The work-around is to stop the server's Java process before you start the server. To
determine which Java process
to stop, open the process identification file for the server at profile_path/logs/server_name/server_name.pid.
The number in the .pid file identifies which Java process to stop.
