Not possible to upload an archive would mean a problem with F5.

I have seen this with other apps running F5, and I think it has something to do with persistence, essentially you want the upload to go back to the same server you were negotiating with when you started the request. Your F5 admin should be able to assist you.
Some general information on F5's here that may help with your discussion: Cookies, Sessions, and Persistence
