Maybe we can set the cache to 3 GB, maximum 4 GB. Also, it would be nice to know the hardware recommendations for the squid service. * It seems that some Atlas jobs are getting killed because of memory limits. CSCS, Leo and Derek will get involved. * The 2000 job limit per VO is causing some headaches to CMS. We will deploy the next Moab version as soon as possible, but not before Christmas. * Also, we agreed on making a round-trip over the cloud's sites to report problems and news in the Operations meetings, not only CSCS. ---++ Action items * item
