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.
