Interpreting errors on CSS 1503

[ross.bridges]

In debugging why random users get an Internet Explorer "page not found" error when connecting through our new content switch to our web servers, I have tracked down the problem from debug logging on the content switch.

The error that appears in the log of the CSS11503 when the user's IE is unable to find the page is:

NOV 10 09:49:18 3/1 101 FLOWMGR-6:

FM_UtilGenericTcpFlowReject: Handling Generic Flow REJECT

NOV 10 09:49:18 3/1 102 FLOWMGR-6:

FM_UtilGenericTcpFlowError: Handling Generic Flow ERROR

Looking on CCO i can't as yet find out what these errors mean. Any advice on where to look would be greatfully appreciated.

This error is on the client side and something caused the CSS to reject the connection. Examples might be the content request spanned more than the configured maximum (default is 6). The delayed

ACK to the client (at 200ms) could not be sent or was responded to with a TCP SYN/FIN or RST or the client closed down unexpectedly.

> FLOWMGR-6: \n FM_UtilGenericTcpFlowError: Handling Generic Flow ERROR

This error is on the server side. The CSS is sending the spanned content request to the server and either did not get an acknowledgement or got an unexpected response or more likely in this case the client

side was torn down. In the example you gave the two log messages came together, So perhaps the client closed down in the middle.

I would suggest to capture a sniffer trace of the problem and see what is going on there.

There might be many reason for this.
