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.
