I took 6 of these runs and extracted which test cases ran in the killed worker. Then I checked for common test cases and I only found tempest.api.compute.admin.test_volume.AttachSCSIVolumeTestJSON.test_attach_scsi_disk_with_config_drive in the intersection of the test case sets. That is also the one that got killed by OOM.
