      • Big backlog of PR
        • Big backlog of PRs due to Code Freeze (Should be over on Monday)
      • Datasetlocks not getting properly deleted #1860
      • Issue with lost source
        • Possible due to race-condition when rules gets STUCK
          • sources are cleared out
          • Only new sources created when transfer is re-submitted, but might take time
          • In this time-window, the replica might be unprotected
          • Possible solutions:
            • Check if there is a REPLICATING replica, and not delete them
            • Keep requests (and sources)?
