On enabling some debug outputs I have discovered that there are some arbitrary packet drops during the transfer causing the file to be corrupted. I am unable to figure out if its a Sming issue or ESP TCP stack issue. I have spent the past three days trying to figure it out but so far no luck which leads me to conclude that its an internal stack issue. Can anyone confirm if ESP cannot handle large file transfers!? Strangely I am able to download huge files from the same server. Just not upload.
Has anyone tried something similar ?, please let me know about your experience.
