Received message XCOMM0780E Txpi  215: Socket send error return value = 1128. What is causing it?

Answer:

This error message is frequently followed by

XCOMM0780E Txpi 215: Socket send error return value = 1124

CA-XCOM is passing back the error return values from TCPIP. You may look up the return values in CEE.SCEEH.H(ERRNO). The high level qualifier of the dataset may vary.

1128 indicates "socket was refused because the process was not listening or because the TCP/IP queue of connection requests was full."
1124 indicates "socket is not connected"

Check on the remote side to make sure you are sending to the right address and port and CA-XCOM is running and the number of requests sent to the remote did not exceed the capacity to process them. If the remote partner is a new installation, particularly a UNIX or LINUX partner, try a loopback transfer on the remote side to make sure that the TCP/IP configuration is correct.
