Operational issues:

• User job failures due to buggy DaVinci version (linked to a buggy xrootd client) last week
  • Users informed about the problem
  • LHCb banned all affected DaVinci versions from Analysis Productions (AP)
    • User jobs are still affected, and there is no easy way to ban certain software version for user jobs
    • Users are encouraged to use AP instead of custom jobs
• Some WNs are using CERN Stratum-1 rather than RAL one
  • That seems to affect ETF tests sometimes (probably CERN Stratum 1 does not do snapshots as often as we do)
