Hi cinder team, we have the issue, that doing backups of big volumes (5TB) fails and cinder-backup get oom killed. Looks like cinder-backup is allocating memory but didn't release it correctly. Badly we are still using cinder queens. Is this a known issue and fixed in newer releases or should I create a bug report? We found a similar bug [1] with backup restore, that got fixed. I guess something like this is also needed for backup create.
