JR50313: MEMORY LEAK WHEN CUSTOMERS USE POLICY SET IN WEB SERVICE WHICH CAN CAUSE java.lang.OutOfMemoryError

Version 8.5 Refresh Pack 6 for the IBM Business Process Manager products
Version 8.5.0 Fix Pack 2 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• When you use an inbound web service with policy set settings,
  a policy set workspace is created for every inbound request and
  is stored in memory without being released after use. This
  causes the memory to keep on increasing and leads to a
  java.lang.OutOfMemoryError.

  ****************************************************************
  A policy set workspace is needed for loading the policy set
  settings. When an inbound request message reaches an inbound
  web service, a policy set workspace is created to load policy
  set data that is configured for the inbound web service. The
  workspace is not released automatically after the request is
  completed.
