The server experienced an error return code from TCP/IP while sending to the SNMP subagent. This message is also issued when the SNMP subagent has an error sending a verb to the server when acting as an SNMP client. This may be a normal event if either side of the connection is abruptly ended, as in the case of terminating the subagent program. The error is reflected in another message for TCP/IP which further describes the error.
The session is ended. Server operation continues. If a message is being forwarded to an SNMP managing node, the message is not sent. If a heartbeat message was being sent to the subagent, this heartbeat message is lost and the server attempts to re-start its session with the SNMP subagent.
If the session is ended as a result of intentionally stopping either the subagent, no response is required. Otherwise, ensure that the TCP/IP protocol stack is functioning by using the tools that come with the particular TCP/IP suite on the platform in use.
