large file upload and Big-IP

If it's a TCP VIP referencing a TCP profile you could create a custom TCP profile with the idle timeout extended higher than the default of 300 seconds. However, I'd be a little surprised if the client was leaving the connection idle for that long.

 

 

If the idle timeout change doesn't fix the problem, it might help to capture a tcpdump of the client and server side traffic to see what is actually happening during a failure. SOL411 has details on capturing/analyzing tcpdumps.
