LO70086: HIGH MEMORY USAGE OF PHYSICAL MEMORY ON 64BIT SERVER

APAR status

• Closed as user error.

Error description

• Both Windows task manager and NSD always show high memory usage
  of physical memory (>85%). This server is running as system
  administration server and no user access happens. Even after the
  customer increased the physical memory from 4GB to 6GB, both
  values are still showing high usage. The server is running
  normally and no performance issue is reported, but customer
  wants to know why physical memory is consumed largely on low
  load server.
  
  Environment:
  Domino 8.5.3FP1 (64bit)
  Windows 2008 R2 SP1 (64bit)
  
  NSD always shows high memory usage even after the RAM is
  increased from 4GB to 6GB. (Windows task manager shows nearly
  the same result.)
