<br>
To avoid you having to pull apart the logs starting ~ [1], we<br>
determined that ze04.o.o was externally rebooted at 01:00UTC (there is<br>
a rather weird support ticket which you can look at, which is assigned<br>
to a rackspace employee but in our queue, saying the host became<br>
unresponsive).<br>
<br>
Unfortunately that left a bunch of jobs orphaned and necessitated a<br>
restart of zuul.<br>
<br>
However, recent changes to not run the executor as root [2] were thus<br>
partially rolled out on ze04 as it came up after reboot. As a<br>
consequence when the host came back up the executor was running as<br>
root with an invalid finger server.<br>
<br>
The executor on ze04 has been stopped, and the host placed in the<br>
emergency file to avoid it coming back. There are now some in-flight<br>
patches to complete this transition, which will need to be staged a<br>
bit more manually.<br>
<br>
The other executors have been left as is, based on the KISS theory<br>
they shouldn't restart and pick up the code until this has been dealt<br>
with.<br>
<br>
Thanks,<br>
