Resolution

The socket return code "errno" and reason code "errnojr" in this message are documented in the z/OS UNIX System Services Messages and Codes.

The error codes can also be found in SYS1.MACLIB in member BPXYERNO.

Errno 1121 is ECONNRESET

Errnojr is 76650446

The first 4 bytes of the reason code identifies the module id or number - 7665.

The last 4 bytes of the reason code is the real reason code, in this case 0446 which means JRSocketConDropped, the socket connection was severed.
Action: The socket connection was dropped. Re-establish the socket connection.
