Builds fail repeatedly without log

Asked by Heinrich Schuchardt

Building OpenJDK on riscv64 takes more than a day. I have repeatedly seen builds fail without any build log. Last time was
https://launchpad.net/~xypron/+archive/ubuntu/merge-from-debian/+build/24487512

This is the only output:

Build status
[FAILEDTOBUILD] Failed to build on riscv64-qemu-lgw01-083 Retry this build

Started on 2022-09-19
Finished 7 hours ago (took 1 day, 17 hours, 42 minutes, 58.7 seconds)

Why is there no build log?

Best regards

Heinrich

It looks like maybe it crashed the builder. At the moment we have no more information than you have. I'll retry that build and see if I can get anything from the resulting logs on the builder itself.

I'm watching "tail -f /var/log/launchpad-buildd/default.log" and "journalctl -f" on the relevant builder now. Hopefully that'll show something useful.

Thanks Colin for looking into this.

My current job is using https://launchpad.net/~xypron/+archive/ubuntu/merge-from-debian/+build/24492450 is using riscv64-qemu-lgw01-062. So maybe you should watch that builder too.

Best regards

Hi Heinrich

I see the build is successful, are we ok to close this question now?

My current build completed successfully. It is still strange why builders
stop after 26 hours without build log. But I guess the reason is hard to
elucidate without a reproducible test case.

Yeah, I watched this and couldn't see anything odd. I suspect that the emulation host in question may have been having trouble - I noticed it rebooted a little over two days ago, so that might well have caused this sort of problem.

The problem is solved. Thanks.
