  • Problem with the Online Alignment conditions

    • ATLAS requested xrootd 4.X, to check if we can use it

Gerhard: do we also upgrade to 4.8.5? no

Marco Ca.: It would be nice if Online moves to 4.9. Gerhard should try to push for it.

Marco Cl.: Can we use ROOT 6.04 for early measurements? Or keep 6.02? (there is still a known memory problem in 6.04)
Not for early measurements, but need to rediscuss on Friday at the PAC.

Ben: there's also another problem with ROOT 6.02 on CC7 (reported).
