  ****************************************************************
  When an exception or error happens before or during the
  parsing of the POST request data, the server stops the
  request's flow but continues to read in and destroy all the
  remaining POST data.  This process could be ineffective as it
  might consume some of the server's resources.
  

Problem conclusion

• The WebContainer code was modified to stop reading the
  remaining POST data if there was an exception or error before
  or during the parsing of POST data.
  
  A new WebContainer custom property needs to be set to enable
  the behavior provided by this APAR:
  
  com.ibm.ws.webcontainer.skipInputStreamReadOnError = true
  (default is false)
  
  Please refer to the following technote for instructions on
  enabling WebContainer custom properties:
  
  http://www.ibm.com/support/docview.wss?rss=180&uid=swg21284395
  
  In addition to the above WebContainer custom property,  an
  HTTP Channel custom property must also be set:
  
  preventRequestBodyPurge  = true (default is false).
  
  Please refer to APAR PI18962 for more detail on the HTTP
  Channel custom property.
  
  The fix for this APAR is currently targeted for inclusion in
  fixpack 8.5.5.4
