|
1 Frame Received for Unknown Socket Pair |
A TCP frame was received for a connection that does not currently exist. |
|
2 TCP ACK Indication Received in Invalid_State |
A TCP layer detected an error in the TCP protocol. This implies that the remote side is not issuing the correct protocol. |

The local application issued a close (abort) and did a block exit where the port file was declared or DSed. All cases cause a reset to be sent. |
|
7 Logical I/O Interface Establishment Failed |
Indicates an internal software error. The interface between the TCP layer and logical I/O failed to establish. |
