I have a job that's kicked off hourly. On 5 of the last 24 runs, I've seen the failure below. This looks a lot like JENKINS-7111, but I'm not using the Timestamper plugin mentioned in that ticket.

This has just started happening in the past day or so, after upgrading to 1.379. Prior to that I was running either 1.374 or 1.375.

The project involved is currently pretty quiet commit-wise, espeically over the last couple days, so the 'hg log --rev' command value should be giving the same results for recent runs.

I also see that these failures are not being logged in the hudson.log file.

The console output is below.
