TCP/IP Socket Errors (&ZSOCERRN)

It is possible that an unlisted return code is an obsolete return code from a previous release of your TCP/IP product.

3—ENOMEM

Out of memory

Determine why the address space is experiencing storage problems

7—EUNSUPP

Unsupported I/O operation

Contact CA Technical Support.

23—EACCES

User or program lacks adequate permission to access this socket. Permission denied

Ensure that the user ID of the address space is in the OBEY list of IBM TCP/IP in the TCPIP.PROFILE.TCPIP file.

28—EDESTADDRREQ

Socket operation requires a destination address

Contact CA Technical Support.

29—EMSGSIZEA

UDP socket could not accommodate a message as large as this one

Contact CA Technical Support.

34—EOPNOTSUPP

The call does not support this type of socket

Contact CA Technical Support.

37—EADDRINUSE

The given address is already in use

Find the process which has the port registered

39—ENETDOWN

Cannot talk to the networking software on this local machine, or the host's network is down.

Check your network and/or TCP/IP stack

40—ENETUNREACH

This host cannot find a route to the specified destination network

Check your network and/or TCP/IP stack

41—ENETRESET

The remote host is not communicating over the network at this time

Check the status of the remote host

42—ECONNABORTED

The local communications software aborted the connection

Check the status of the TCP/IP address space

43—ECONNRESET

The peer process has reset the connection

Check the peer and determine the reason for its termination

44—ENOBUFS

The operating system did not have enough memory to perform the requested operation

Check your network and/or TCP/IP stack

47—ESHUTDOWN

The connection has been shutdown

Contact CA Technical Support

48—ETIMEDOUT

The destination host did not respond to a connection request

49—ECONNREFUSED

The destination host refused the socket connection

Check the status of the remote host

50—EHOSTDOWN

Socket operation failed because the destination host was down

Ensure that the destination host is active and retry

51—EHOSTUNREACH

Socket operation failed because the destination host is unreachable

Ensure that the destination host is active and retry

52—EPIPE

The peer process closed its socket while the local task was still writing data to the connection

Check the status of the remote host

63—EIO

I/O error occurred

Check the TCP/IP region for messages

64—ECONNCLOSED

Connection closed by peer

Determine why peer closed connection

65—ESOCKCLS

Socket closed

No action-socket closed by process

66—ENOPIDS

No process IDs available for ping or traceroute

Retry operation

67—ENOPORTS

No ports available for traceroute

Retry operation

68—ESHPORTCLS

Shared port closed

No action-shared port closed by process; will be opened later in processing

69—EUNKSERVER

Unknown server

Check the server name and then retry.

70—EINVPORTNUM

Invalid port number

Check the port number and then retry.

71—ESERVERNAMEINUSE

The given server is already in use

Find the process which is using the port.

72—EDNRNOTFND

Host name or address not found for SOLVE DNR

Check the host name and then retry.

73—EDNRNORSP

SOLVE DNR timed out

Retry operation

74—EDNRBADNAME

Invalid domain name for SOLVE DNR

Check the domain name and then retry.

75—EDNRERROR

SOLVE DNR error (for example, send/receive error or storage error)

Check descriptive text returned with error code

999—EOTHER

Vendor-specific error

See ZSOCVERR and vendor TCP/IP error codes
