[ceph-users] librbd Image Watcher Errors

Hello, with cron i run backups with backurne (https://github.com/JackSlateur/backurne) which is rbd based. Sometimes i get those messages: 2020-08-05T18:42:18.915+0200 7fcdbd7fa700 -1 librbd::ImageWatcher: 0x7fcda400a6a0 image watch failed: 140521330717776, (107) Transport endpoint is not connected 2020-08-05T18:42:18.915+0200 7fcdbd7fa700 -1 librbd::Watcher: 0x7fcda400a6a0 handle_error: handle=140521330717776: (107) Transport endpoint is not connected 2020-08-05T18:45:13.496+0200 7fcdbd7fa700 -1 librbd::ImageWatcher: 0x7fcda400a6a0 image watch failed: 140521330717776, (110) Connection timed out 2020-08-05T18:45:13.496+0200 7fcdbd7fa700 -1 librbd::Watcher: 0x7fcda400a6a0 handle_error: handle=140521330717776: (110) Connection timed out 2020-08-05T18:58:01.408+0200 7fc66ffff700 -1 librbd::ImageWatcher: 0x7fc65c00a770 image watch failed: 140490057987152, (107) Transport endpoint is not connected 2020-08-05T18:58:01.408+0200 7fc66ffff700 -1 librbd::Watcher: 0x7fc65c00a770 handle_error: handle=140490057987152: (107) Transport endpoint is not connected Any idea what this indicates and how it could be solved?
