Comment 3 for bug 1892029

I had a different experience reproducing this issue. The machine did not reboot, but the machine agent restarted. When I rebooted the centos machine with `shutdown -r now`, the machine agent was lost for a bit, then came back as expected.

The proxyupdater error is unrelated, it happens with that worker starts, but does not cause the machine agent to fail. I've filed a new bug for it lp:1901069.
