Today we've had a few intermittent failures on our Jenkins environment
that I've seen and hopefully will have managed to fix shortly. (Not
intermittent errors in tests themselves.)
-
One of the slaves ran out of space in ~/tmp, due to some very large
files generated by npm that it hadn't cleaned up. I've added a cronjob
(https://git.io/vwPsQ) to remove these. -
Thread creation errors started appearing with the release of Bundler
1.12.0, which caused the Jenkins agent to crash, go offline, and try to
resume. This then caused Xvfb related errors as it didn't get shutdown
properly.
I've increased the nproc limit to cope better with the requirements of
Bundler (https://git.io/vwP5O), but I need to complete a restart of each
slave to pick this up. I'm starting this now, so expect a slowdown of
jobs in the queue over the next few hours as capacity will be lower.
Hopefully this will stop the errors once rolled out.
Please let me know if you still see similar issues still at the start of
next week.
