Description of problem:
Geo-replication session becomes faulty after a while of syncing.


Version-Release number of selected component (if applicable):
3.11.2-1

How reproducible:
Setup a session for geo-replication between a local site and a remote one to sync two volumes. Both backend storages are EXT4. The data is backups of servers containing many hard and sumlinks.

Actual results:
The geo-replication session becomes faulty at the same exact point every time I try.

Expected results:
The sync should finish with no errors.

Additional info:
