Dear maintainer(s),

Your package has an autopkgtest, great. However, it fails from time to
time.
From
	https://ci.debian.net/packages/p/puma/testing/amd64/

openssl/3.0.8-1 failed
	https://ci.debian.net/data/autopkgtest/testing/amd64/p/puma/31159611/log.gz
openssl/3.0.8-1 passed
	https://ci.debian.net/data/autopkgtest/testing/amd64/p/puma/31166222/log.gz

s390x, failed:
	https://ci.debian.net/data/autopkgtest/testing/s390x/p/puma/31163926/log.gz
	https://ci.debian.net/data/autopkgtest/testing/s390x/p/puma/31207049/log.gz
	https://ci.debian.net/data/autopkgtest/testing/s390x/p/puma/31207176/log.gz

then passed
	https://ci.debian.net/data/autopkgtest/testing/s390x/p/puma/31207506/log.gz

My understanding is that the error is a different in the three failures
on s390x.

Could you please have a look?

Sebastian
