The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here:

https://people.debian.org/~sanvila/build-logs/202504/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:zookeeper, so that this is still
visible in the BTS web page for this package.

Notes:

- Actually, this has been happening since bookworm at least, and that's why
I'm using the bookworm version for the report. The problem happens im both
bookworm and trixie/sid.

- The error happens randomly, not always. But it happens too often.
To be precise, the failure rate I'm getting here is around 70% of the time
on machines with 1 CPU and 40% on machines with 2 CPUs. I do believe
this is not suitable for release, but will be happy to report this
as important if it serves to concentrate on fixing the bug and
not discussing about the severity.

Thanks.
