z/OS Communications Server: IP Messages Volume 3 (EZY)
SC27-3656-00

hh:mm:ss.th socket_error, socket__call ERRNO=errno

Explanation

An error occurred during a socket call. The Listener processing at the time of the error and the socket call are given by socket_error and socket_call.

errno is the UNIX System Services return code. These return codes are listed and described in the return codes (errnos) information in z/OS UNIX System Services Messages and Codes.

A description of each of the errors is given below:
Unable to accept new connection, ACCEPT
An error occurred when the Listener attempted to complete a connection in response to a connection request from a client.

Procedure name: ListenProcess

Unsuccessful binding to communication port, BIND
The Listener was unable to bind the port that it is to use for accepting connection requests from clients. The port is specified by the PORT parameter of the LISTENER statement.

Procedure name: main

Socket CLOSE error:
An error occurred when the Listener attempted to close a connection.

Procedure name: ListenProcess, ReleaseProcess

Error transferring connection to server, GIVESOCKET
An error occurred when the Listener attempted to pass control of the client connection to the server.

Procedure name: CreServPro

Failed to connect to TCPIP address space, INITAPI
An error occurred while attempting to connect to the TCPIP address space. The TCPIP address space that is used is specified by the ADDRSPC parameter on the TCPIP statement.

Procedure name: main

Failed setting socket to listen mode, LISTEN
The LISTEN call, used to enable the socket connected to the listening port for incoming connections, resulted in an error.

Procedure name: main

Socket READ error:
An error occurred when the Listener attempted to receive data sent from a client program. Further information about the client is provided by message EZY1032I, which is issued after this message.

Procedure name: ReadInputProcess, ReadTRMProcess

Error waiting for communications event, SELECT
The SELECT call, used to wait for connection requests and data for implicit transactions, has resulted in an error.

Procedure name: main

Failed to obtain a socket to listen on, SOCKET
The Listener failed to acquire a socket for binding to the listening port.

Procedure name: main

Server failed to take connection, TAKESOCKET
The Listener issued a GIVESOCKET and the server failed to issue a corresponding TAKESOCKET.
Note: ERRNO is not applicable to this error.
Socket WRITE error:
An error occurred when the Listener attempted to send data to a client program.

Procedure name: WriteRSMProcess

System action

The system action depends on the error. If the error occurs during startup processing or during a SELECT call, the Listener ends. Otherwise, the connection that received the error is closed.

Operator response

For errors encountered during startup processing, check that the configuration file TCPIP and LISTENER parameters are correct. Otherwise, proceed based on the value of errno.

System programmer response

Assist the user as required.
