Comment 12 for bug 1491688

I just got this error:
2015-10-29 20:45:22 ERROR juju.worker runner.go:223 exited "rsyslog": x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "juju-generated CA for environment \"rsyslog\"")
2015-10-29 20:45:26 ERROR juju.worker runner.go:223 exited "rsyslog": x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "juju-generated CA for environment \"rsyslog\"")

It's repeating every 3s in this particular unit's logs.

All clocks are fine: http://pastebin.ubuntu.com/13002468/

For a wile the agent was reporting this:
  landscape-client/25 unknown allocating 1.24.6 10.245.201.10 Waiting for agent initialization to finish

That's when I logged in and spotted the rsyslog error. While I was poking around, without changing anything, the deployment eventually finished, but the error is still going on every 3s in that particular unit log.
