After upgrading to UnityOS 5.1.x, there is a substantial decline in SMB/NFS performance and overall TCP throughput.

Deleting async replication sessions of multiple thick LUNs might cause disk overload and impact other services.

Shrink operation on a thick file system does not return the space back to the pool.

Replication session goes to halted state.

The NAS server is showing degraded in the user interface because it is unable to perform bind operation with LDAP server using anonymous user.
