Public bug reported: The bug fixed in https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1334916 (1:6.9p1-3) was never released for Ubuntu 14.04. The symptoms in openssh-server 1:6.6p1-2ubuntu2.8 are exactly the same as reported in that bug.
Unfortunately, moving from 14.04 to a more recent release like 16.04 isn't an option for us. Neither is reverting to the previous release for 14.04, due to the security vulns that were fixed in the latest release. I'm happy to supply more information if required.
