@yaronkaikov

I don't know what got it started

But it's the Jenkins client code failing, which means you'll need your team to help figure it out...

This suggest communication issues between builder and master

for now seems to be happening more often in artifact pipeline:

Similar problem happens not on the checkout but the stream in long-running CI jobs. It is 100% failure.
It makes all the pipeline stages, after the test run one, to fail - no resources deletions, no logs...

@vponomaryov

The builder probably got killed, the question is why, and by whom.

@vponomaryov

The builder probably got killed, the question is why, and by whom.

It is stable behavior, all my long running jenkins jobs fail this way.
It doesn't look like manual activity.

Probably, some cleanup logic somewhere got changed and now cleans up builders without any regards to utilization of it.

looking in AWS CloudTrail -> Event history

the build was stopped after the error occurred in your job

so it's not a builder that died

so the next theories

  • that it's influence of something else that used the builder, we can have up to 4 job sharing a builder
  • communication issues between jenkins master in GCP to the builders in AWS

so I would start by changing it for this region to stop sharing the builders

no it's not getting auto updates

We can't downgrade Java back to version 11, cause we already upgraded Jenkins server to version 2.488 - where Java version 11 is not supported and in addition java 11 reached end of life.

We can downgrade to Java 17 - but I'm not sure it will help.

Will it help to downgrade Java version to 21.0.4?

I did meant to downgrade to that one, not to 11

I think those new HTTP limit aren't aligned between builder and master, and might be the root cause
