RAL stage-out timeouts:
    * Rucio clients 1.21.9 should be deployed ~ now
    * to follow-up on effectiveness of the 'fix' :
 Still seeing jobs with same timeout errors, with the new Rucio version. With a few more statistics will pass back to ATLAS Rucio and DDM experts.
 

Stage-in problems:
  * Useful discussions yesterday; no 'smoking gun'.
  * Aim to correlate between ATLAS reporting and Echo logs.
