  - <big> Grid-Operator-on-Duty handover </big>
    
    From: DECH / Italy
    To: CE / UK/I
    
    Report from DECH COD:
    
    One ticket escalated to the Ops meeting: GGUS #34400 (https://gus.fzk.de/ws/ticket_info.php?ticket=34400)
    Site fails because SAM uses old lcg-utils. ROC_CERN promised already to upgrade but obviously did not manage so far.
    Report from Italian COD:
    
    Suggested that the site IL-IUCC (ROC-SEE) be suspended.
    #37110 (SRM)
    #36185 (SE, same pb., closed)
    #36262 (CE)
    These tickets have been open for long time (early May) with no feedback. The site has been in downtime for a long time.
    Not escalated last Friday: we COD tried to give suggestions on Thursday, then we had big problems at CNAF on Friday.
    Checked today, no feedback.

    Speaker: Daniele Bonacorsi
  - <big> LHCb report </big>
    
    LHCb is running its DC06 activity at full regime. Stripping activity pointed out issues at RAL (still jobs cannot get there after the incident with the CMS rogue user killing the system with 10K jobs at once), IN2p3 (data access problem with gsidcap, Philippe sent all information through the GGUS ticket open for debugging their SRM/SE system), CNAF is in downtime, SARA: failures uploading output data.
    
    CIC broadcast information: received one for IN2p3, reason: queues drained (which is not very useful and informative) and one for GRIF: scheduled intervention, reason: unexpected hardware failure (but how can then be the intervention scheduled?).
