Tier1s/Tier2s • a few problems with some Tier1 • CNAF LFC: file allocation limit reached, limit raised • CNAF SRM: storm daemon stuck, relaunched • SARA-MATRIX SRM: problems with 8 pool nodes that crashed, all with the same hardware, but not yet understood why; workaround should be in place • TAIWAN-LCG2 SRM: CRL expired, cron job for upfdating was stopped; relaunched • Several T1s MCTAPE: high load was responsible for some error beginning of last week • RAL: network problems on monday early morning, fixed by late morning on the same day • minor problems with a few Tier2s • GGUS tickets promtly submitted by ADCoS shifters and always managed by the sites in a timely way
