Currently trying to understand why the ssh connections to c1sus are flaky. This morning, every time I tried to make the c1sus model on the c1sus machine, the ssh session would be terminated at a random spot midway through the build process. Eventually restarting c1sus fixed the problem for the moment.
However, previously in the last 48 hours, the c1sus machine had stopped responding to ssh logins while still appearing to be running the front end code. The next time this occurs, we should attach a monitor and keyboard and see what kind of state the computer is in. Its interesting to note we didn't have these problems before we switched over to the Gentoo kernel from the real-time linux Centos 5.5 kernel.
