        • <big> EGEE issues coming from ROC reports </big>
          1. [ROC France]: Any progress for action 000212 on Steve (i.e. Publishing Production Role restriction from CE queue)?

          2. [ROC DECH]: SAM had some problems this week ...

            SAM Problem: (network) problem with the CERN BDII used by the RB/WMS for job submission.

            SAM Problem: File missing for host certificate test.

          3. [ROC Italy]: Issue from INFN-T1:

            We noticed this problem on the GOC DB: in a open downtime, when status is changed, for example from Risk to Outage, the history is lost, so if we open one for "Risk status" and after 3 days we pass in "Outage status" for the GOC DB we have been always in "Outage Status". It seems one solution is to close the down of "Risk status" and open a new one for "Outage status".

          4. [ROC South Eastern Europe]: 99% of SEE WNs are now SL4 with gLite 3.1. We are also testing the SDJ configuration as it is described at http://egee-intranet.web.cern.ch/egee-intranet/NA1/TCG/wgs/SDJ-WG-TEC-v1.1.pdf

            Do other regions have some experience to share on this matter?

          5. [ROC UK/I]: SAM still reports sites as failing when there is a well identified grid wide failure. What is the timeline for no longer publishing these failures to sites (who when they are published spend time trying to figure out the problem).
