• low on simulation. But plenty of evgen. Removing sim-only restrictions on PQs, eg. P1, but nothing in DE cloud, I think?
• When no LOMEM we can drain some PQs since 1 HIMEM running puts it over the meanrss.
  • now have emergency switch to disable meanrss throttling. Used only once so far.
• Lack of FIFO on BNL tape since alays take the tape with most files wanted
  • small dataset, or eventpicking always lose out, then timeout 
  • victim of successful smart writing
  • will ask others - what about KIT?
• FTs of data transfer will start sending mails to cloud support
