Public bug reported:

The following tests exited without returning a status
and likely segfaulted or crashed Python:

        *
tempest.api.compute.admin.test_volume.AttachSCSIVolumeTestJSON.test_attach_scsi_disk_with_config_drive[id-777e468f-17ca-4da4-b93d-b7dbf56c0494]


And in the syslog: https://zuul.opendev.org/t/openstack/build/f5aa5edd4d354c2685fc1f3e13d0ef77/log/controller/logs/syslog.txt#3688

Example run:
https://zuul.opendev.org/t/openstack/build/f5aa5edd4d354c2685fc1f3e13d0ef77

I see this happening in multiple jobs in the last 10 days:
* nova-ceph-multistore 14x
* nova-multi-cell 1x
* nova-next 1x
