It is 100% reproducible when I scp a file (>100 kB) to a machine on the other side. Copying a file of any size in the other direction (from the remote machine) to my box works fine. I see somewhat similiar problems doing large HTTP POSTs to the remote machine or when I run a remote X application. I tried several versions of openconnect 4.06, 4.07 and 4.99 on linux 3.8.0-22 and see this behaviour with all versions. On the same system everything works fine by just swapping the kernel booting to 3.5.0-27.46 (latest from Quantal Quetzal). Additional information (e.g. tcpdump output) is at launchpad (bug 1185884) where I originally reported to bug.
