LHCb:

• Checksum setup was incorrect on the preprod farm last week.
  
  • As a result, all downloads were failing
• Issues with CNAF-RAL transfers
  
  • CNAF storage uses authentication key in their http headers, our xrootd version only accepts Authentication (case sensitive)
  • Xrootd upgrade attemted yesterday, caused even more problems (though the issue with the keys was solved)
  • Rolled-back to the old version
• After the prefetch change roll-out some WGprod jobs are still causing xrootd proxy to run out of memory
  • The scale of the problem is not clear yet
• Copying to RAL from RRCKI is finished
  • Some final cleanup may  be necessary
• Lists of files affected by xrootd bug are ready
