Hi, I have still been working on this issue. I will send you the log files today. The only thing I wanted to ask is that the log file on the client side seem to come out in an XML format and not a plain text format. Is this acceptable or do I need to do something different. I checked on our deployment config and there is no clustering or load balancing. I also believe that the server side http session is set to 1200 seconds and the ulc keep alive interval is at 900 seconds. In either case the error I am getting happens as soon as the application launches (before any UI shows up/within maybe 10 seconds of the web start launching) so I doubt it is a time out issue.
Let me know if the xml log file is ok. Thanks.
