Bug #4493
Updated by Tim Pierce about 10 years ago
Job "qr1hi-8i9sb-z8jwujrvgcvmr9h":http://crvr.se/qr1hi-8i9sb-z8jwujrvgcvmr9h failed with this in its error log:
<pre>
2014/11/09 17:47:58 Error response from daemon: engine is shutdown
</pre>
That is an internal Docker error message.
A quick scan of the Docker issue tracker turns up no existing open issues that are obviously related to this.
