Comment 5 for bug 1831899

Hi Robert,
you may upload them to IBM box, I have an account there and may download them to the Canonical network - that's how I also do it with my IBM project mgr as well in case of dumps or other larger files.

Thanks for sharing the additional information so far.

But I'm still wondering about the libc version.
The libc version in Bionic is 2.27, but I see 2.23 in the above strace which is the one from Xenial.

rmadison --arch=s390x libc6 | egrep 'xenial|bionic'
 libc6 | 2.23-0ubuntu3 | xenial | s390x
 libc6 | 2.23-0ubuntu10 | xenial-security | s390x
 libc6 | 2.23-0ubuntu11 | xenial-updates | s390x
 libc6 | 2.27-3ubuntu1 | bionic | s390x

On your system you should see the following output, pointing to 2.27:

$ apt-cache policy libc6
libc6:
  Installed: 2.27-3ubuntu1
  Candidate: 2.27-3ubuntu1
  Version table:
 *** 2.27-3ubuntu1 500
        500 http://us.ports.ubuntu.com/ubuntu-ports bionic/main s390x Packages
        100 /var/lib/dpkg/status

Please can you double check with 'apt-cache policy libc6'?
It's important to have the correct libc6 and in case it's a 2.23 where it's coming from:
sudo find / -iname "libc-2.*.so"
