          2009-09-03: release of gLite 3.1 Update 55 to production in preparation This update will contain:

          1. CREAM CE 1.5 (PATCH:2666)
            • VOMS server host certs are not required anymore in the CREAM CE node (the /etc/grid-security/vomsdir/*/*.lsc files are sufficient)
            • First release of new BLAH blparser for LSF and PBBS/Torque (use of batch system status/history commands instead of parsing the log files)
            • IPv6 support for BLAH
            • Several bug fixes, in particular:
              • Fix for a problem with purge (not deleting the job sandbox dir in some cases)
              • Fix for a problem for which there could be at most 32000 active jobs per user
              • Fix for a problem for which the produced accounting logs (used by APEL and DGAS) was not properly filled if the CREAM CE is not the Torque server
          2. Update of the ICE component of the WMS (PATCH:2862)
            • Improvements in performance and scalability
            • Improved use of memory
            • Use of jobdir instead of filelist as input for ICE

          • REMINDER: Security vulnerabilities

            Last month several alerts were sent to all sites about critical security vulnerabilities in the Linux kernel (CVE-2009-2692 and CVE-2009-2698). A number of sites in the academic community have subsequently reported root compromised hosts via these vulnerabilities. Yet, it appears a significant number of EGEE sites have still not applied the security patches - it is essential to actively and urgently ensure all the sites in your region have applied these security patches.

          • Call to encourage sites to move to the most recent version of WMS available in gLite 3.1, which corresponds to glite-WMS 3.1.21-0 in the gLite repository (known with the nick name of WMS 3.2) This update contains a new release of the WMS which is a complete redesign of the service. For a summary of the changes introduced in this version, please check these web pages: https://twiki.cnaf.infn.it/cgi-bin/twiki/view/EgeeJra1It/ReleaseNotes2597 http://web.infn.it/gLiteWMS/index.php/information/38-software/59-320relnotes NOTE that at last week's GDB, WLCG agreed to request all WLCG sites to upgrade to this version by the end of October.
