          3. There were some problematic nodes turned off on GOCDB and the SAM test did not run this node. I closed these tickets. Such as :
            • ticket 6379 FRJ-IF
            • ticket 6469 INFN-TORINO

          Issues from EGEE ROCs:
          1. Nothing to report
          Release News:
          • Item 1
            • Item 1.1
          • Item 2
        • <big> EGEE issues coming from ROC reports </big> 5h
          1. Central-Europe: Do gLite software procedures contain any security vulnerability check process? Who carries it out?
          2. IN2P3:
            1. We are experiencing memory problem with SL4_32. As a consequences, we had to reduce the number of job slots by WN. At the time being we have only 7 job slots for 8 CPUs (16GB RAM) by machine. This is still possible that we should reduce again the number of job slots as the problem still appears sometimes. We are also trying to solve the problem at the OS level, but no solution has been found for now. Anyway, this problem should disappear with SL4_64, so the question is: when can we get an official release of glite WN for SL4_64? Would it be possible to try a pre-release ?
            2. Lot of CMS jobs (1500) were lost because of a mini blackhole created by 10 misconfigured WNs. The problem has been hardly identified because of memory problems occurring at same time with SL4_32. This mine blackhole is now closed.
        • <big>Removal of lcg-job-monitor.cern.ch</big> 5m
          The unused and non working service: https://lcg-job-monitor.cern.ch:8443/job-monitor/job-monitor.cgi will be removed later this week.
        • <big> gLite Release News</big> 15m
          A new null release was made: glite 3.1 Update 5. This removed some 3rd parties from the gLite externals that were available from DAG anyway.
        • <big>gLite Progress to SL4.</big> 10m
          SA3 to give an update on progress of service nodes to SL4.

          Speaker: Oliver Keeble (CERN)
        • <big>Life Time of SL3 Services after an SL4 Release</big> 5m
          It is the wish of SA3 that one month after an SL4 release of a service is made support for the SL3 version will be stopped. Deployment activities within SA1 require that any problems with the SL4 service will of delay the expiration of the SL3 service.
        • <big> End of life for SL<b>C</b>3</big> 15m
          SLC3 reaches end of life in two days time and updates will no longer be guaranteed. Updates for SL3 are still available until 2010.

          Current situation searching for SLC3 sites in the information system we see a distribution of SubClusters by country domain name of.

    • Last week we had at CNAF problem due to the shared area not working. The problem was related to the migration of the shared areas to GPFS. This suggestes that any important changes in site configuration should be always broadcasted at a high level.
