I am trying to connect remotely to another linux server. When my servers are started as user 'A' and I connect through sqlplus as system/password@hos from the user 'oracle' i get this error message from the logs:

TNS-12518: TNS:listener could not hand off client connection
TNS-12547: TNS:lost contact
TNS-12560: TNS: protocol adapter error
TNS-00517: Lost contact
Linux Error: 32: Broken pipe

Our processes are set to 2000 so it isn't the processes. Can anyone help me out?
