Ubuntu 11.04 host and slave on AWS.
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.
The full log follows:
