Debug transfers from RWTH are ok, so a proxy issue excluded). Transfer actually ended ~31/1/2010, with the transfer of the last two files from RWTH (2) Subscribed both at CSCS and PSI. As data is not flowing from CSCS, all sites but CSCS excluded from dowload agent at 2010-02-04 10:12. Added =-ignore '*'= at 2010-02-04 12:12:10. No actual effect as with the last modification all transfers were routed from RTWH and FNAL. -- Main.LeonardoSala - 2010-01-28 --- %ICON{arrowleft}% Go to [[CMSTier3LogXX][previous page]] / [[CMSTier3LogXX][next page]] of Tier3 site log %M%
