          The error indicates that the system area of the repository is corrupted (this is where the locks node is stored) which shouldn't happen normally, as users shouldn't have direct contact with it.

           

          Please give us more information regarding your use case & configuration - it appears you are using locks. Are you running in a cluster ?

           

          Also, try to update to the latest 3.x version - 3.7.1 - and check if the error is still there.
