Jenkins missing many jobs

[avivkeller]

Many jobs are currently returning 404s on https://ci.nodejs.org, including node-test-pull-request. It seems as though these configurations have vanished.

FYI @nodejs/build / @nodejs/build-infra / @nodejs/jenkins-admins

I've solved it with a reboot. It's the second time it happens (first time was on Jan 31).
Jenkins logs contain this error:

Just saw this - thanks @targos - I took a look at it seems ok now after the restart. That is a little bit concerning though if it's now happened a second time. I wonder if we could get away with a "reload configuration from disk" instead of a full restart if we see it again. Curious as to what "r" is though 🤔

There seems to be some machine that are unable to clone the repo:

Another git process seems to be running in this repository, e.g.
an editor opened by 'git commit'. Please make sure all processes
are terminated then try again. If it still fails, a git process
may have crashed in this repository earlier:
remove the file manually to continue.

Hmmm so that lock file is not currently present on the mnx workspace machine, although the red status looks to be an out of space condition on the softlayer debian machine ... I've taken it offline for now Re-enabled after [log rotation](#4024 (comment) although it's still quite full).

Related issues:

• debian12-x64 cannot run CITGM (No space left on device) #4221
• No space left on test-softlayer-debian12-x64-1 #4024

E.g. https://ci.nodejs.org/job/node-test-commit-linux/68529/console

So far subsequent invocations of the job appear to be ok 🤞🏻
