  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
