  Operational issues:
  
  Upload failures on RAL (WNs) -> CERN channel
  
  no updates.
  
  Issues on WNs last Sunday
  
  Both Job and transfer failures were present;
  
  The most meaningfull error message came from one of the jobs -- runtime/cgo: pthread_create failed: Resource temporarily unavailable;
  
  The issue disappeared on Monday;
  
  Might be some PID limit excess, Tom would like to upgrade it to the newer version (after the break, obviously);
  
  Ticket GSTSM-277 is opened.
  
  LHCb pilots are killed at RAL due to memory excess
  
  That looks suspicious since all types of jobs are suffering from it
  
  Could it be some wrong memory accounting?
  
  Some WNs have >0 values in cvmfs IO error counter, it causes warnings in ETF tests.
  
  Other:
  
  Writeable WN GW sandbox deployed to a few WNs on the preprod farm last week
  
  Did not work
  
  A few bugs found, to be fixed (in the new year)
