Description
Description:
Cbbackupmgr segfaults when taking a one off backup service backup while using Samba.
Steps to reproduce:
- 3 nodes with the backup service running on all nodes.
- Created a samba share and mounted it on all 3 nodes.
- Created a repository which takes the mounted folder as the archive location.
- Took a one off backup.
What happens:
The backup fails with the following error present in the logs:
