  This made the memory keeps on increasing and leading to
  java.lang.OutOfMemoryError.

  ****************************************************************
  An policy set workspace is needed for loading the policy set
  settings. When an inbound request message  reached inbound web
  service we will create a policyset workspace to load policy
  set data configured for this inbound web service. The
  workspace will not be released automatically when the request
  is complete. We need to add code to delete that after use. The
  same happens when you use web service integration to issue an
  request to the target web service server with police set
  settled.
  

Problem conclusion

• A fix is available for IBM Business Process Manager V8.5.0.1
  to release the policy set workspace after use.
