LO58189: HTTPJVMMAXHEAPSIZE MINIMUM SETTING IS 256MB

APAR status

• Closed as user error.

Error description

• From Technote 1431525
  
  Starting with Domino 8.5 release a new ini setting became the
  default for
  Domino servers running the http task. That setting is
  HTTPJVMMAXHEAPSIZE and
  the default size was set to 256MB (megabytes). The setting is
  specifically
  targeting the JVM being used by the HTTP process. The change was
  made to
  accommodate Xpages which uses the JVM on the server.
  Administrators looking  at
  the server's notes.ini after an install would see the setting
  -
  
  HTTPJVMMaxHeapSize=256M
  
  In 8.5 this was not changeable by the Administrator. This
  ability to modify the
  size was added to the 8.5.1 version of the product as documented
  in TN#1377205
  though the default value of 256MB was still the default.
  
  Starting with 8.5.2 the default value will be set to 64MB. The
  first time the
  server starts up if the HTTPJVMMaxHeapSize is set to 256MB it
  will be reset to
  64MB. A new setting will be placed in the server's notes.ini
  named
  HTTPJVMMaxHeapSizeSet=1. This will keep the server from
  resetting the HTTP JVM
  heap size on subsequent restarts of the server or HTTP task.
  Adminstrator's can
  use HTTPJVMMaxHeapSize to set any size they wish for the HTTP
  processes heap
  size and if the ini HTTPJVMMaxHeapSizeSet=1 is present the
  server will adhere
  to the size set.
  This is only done for 32 bit platforms. The default heap size
  for 64 bit
  operating systems is 1 Gigabyte.
  
  On Iseries the minimum allowable size is 256 MB.
  
  Customers running multiple servers who are not using xpages do
  not need to set
  the JVMMaxHeapSize to this size, 64mb is enough.
  
  A hotfix was created to allow the size to be set to 64MB,
