Description
When files are continuously created and deleted from a CephFS volume accessed through Samba with libcephfs (Samba's vfs_ceph module), a steady increase of used memory is observed. The growth is relatively slow but constant and eventually it triggers the OOM killer.
The test I used to reproduce it was:
- while true; do dd if=/dev/zero of=/mnt/samba/file bs=4k count=1 status=none; rm -f /mnt/samba/file; done
This can be run in parallel using different files to make the leak to happen faster.
