Frequently Queried Log Messages Chapter 4 Using the CSS Logging Features Table 4-8 Cisco 11500 Series CSS Log Messages (continued) Log Message (sys.log: Subsystem Name, Level, and Message) FLOWMGR-6: \n FM_UtilGenericTcpFlowReject: Handling Generic Flow REJECT FLOWMGR-7: Allocation for a vector-loaded flow, where theFlow = 840ef5b0 Cause and Resolution The CSS rejects a connection, either due to issues with the client side or the server side of the connection. When this log message occurs as a result of the client side connection, the issue could be due to a content request that spans more than the configured maximum (default is 6). Other reasons could include: • A delayed ACK could not be sent to the client (at 200ms) • A delayed ACK is sent to the client, and the client responds back with a TCP SYN/FIN/RST handshake sequence. • The client side closes down unexpectedly. When this log message occurs as a result of the server side connection, the issue could be due to the CSS sending the spanned content request to the server and did not get an acknowledgement from the server or received an unexpected response (for example, due to the flow being torn down to the client side). If this message appears frequently in the log, contact Cisco Systems TAC. This is an informational message. No further action is required. 4-40 Cisco Content Services Switch Administration Guide OL-5647-02
