Operations News

  • (Tue) Latest errata, kernel applied to all SRMs and rebooted.
  • 2.1.12 installed and being prepared and tested for repack upgrade

Operations Problems

  • Still seeing occasional problems on ATLAS SRM with failed requests, but no more crashing since 2.11-1 upgrade. CERN have now seen this problem, meaning it's a genuine bug in the CGSI_gSOAP package. Too low level to worry about -> parking.
  • Wrong checksum algorithm in xroot client libraries - need to upgrade them on disk servers

Blocking Issues

  • none
