Slide-O-Mix commented on JENKINS-12047:
---------------------------------------
It's trying to get the environment for the build, which apparently happened on
a slave. I can wrap this call up in a try/catch, but if it doesn't succeed,
other parts of the email sending process may fail still as the EnvVars are used
in several places.
> ERROR: Could not send email as a part of the post-build publishers.

> Key: JENKINS-12047
> URL: https://issues.jenkins-ci.org/browse/JENKINS-12047
> Project: Jenkins
> Issue Type: Bug
> Components: email-ext
> Environment: Ubuntu 11.04 host and slave on AWS.
> Reporter: mcrooney
>
> Our cron box, a Jenkins slave which runs most of our tied jobs, got
> overwhelmed with CPU and jobs were failing. This made sense, but it didn't
> send failure emails even though the jobs were failing, which was quite
> unfortunate as it meant we were failing to update production data for a few
> hours until we noticed. It seems to be relying on a healthy connection to the
> slave in the case of a failure, which might be the cause of the failure in
> the first place.
> I'm not actually sure if email-ext is the root culprit or not, though it is
> configured for affected jobs.
