  ****************************************************************
  Whenever any FFDC file is created, there is no control on the
  size of that file. It could vary as per the size of exception
  dumped, which can eat up the filesystem. In order to control
  this, a new feature has been introduced.
  

Problem conclusion

• In order to control the size of FFDC incident file, we can
  make use of one property which is present in ffdc
  configuration files.
  
  There are three files present in WAS_HOME/properties which can
  be configured to control size of file.
  These files are
  
  ffdcStart.properties
  ffdcStop.properties
  ffdcRun.properties
  
  In all the above three files , there is a property already
  present IntrospectMaxSize which should be configured for
  controlling size.
  
  IntrospectMaxSize, number of bytes to be used when using the
  introspector has a default value of 1024 kilobytes. This means
  that if you will not modify this value after installation, you
  will not see FFDC incident files more than 1 megabytes.
  
  Range for this parameter is from 10 kilobytes to 100
  megabytes, which mean that if someone will try to configure
  the value which is outside this range will be forced to use
  the nearest limit value.
  
  ie. If someone configures 20480000 as a value for
  IntrospectMaxSize , then value set will be 100 megabytes as
  the value configured is out of the permissible range.
  Similarly, if some tries to put value as 1, then value will be
  set to 10 kilobyte as 1 is outside of the permissible range.
  
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 8.0.0.10 and 8.5.5.4.  Please refer to the
