erlang ssl_esock - upload bandwidth nearly 100%, why?

I start gwibber and it maxes out my network upload, around 11-14KB/s (max upload is about 16KB/s). It seriously slows down my networking. I have to kill a process "ssl_esock" to get it back to normal.

I have noticed that it's sending something to Canonical servers (couchdb one ubuntu com).

1. What is being sent?
2. Why does it choke my upload?
3. How do I stop it from being sent?
4. How do I stop it using up my bandwidth?

Process number in question is 4100, according to "sudo nethogs eth1":
