Problem summary

• If a BPD contains an Event Gateway with multiple Intermediate
  Message Events that specify 'Durable Subscription' then
  existing Durable Messages are not delivered to instances of this
  BPD even if the correlation matches.
  
  PROBLEM DETAILED DESCRIPTION:
  When a BPD activates during a navigation transaction an Inbound
  Message Event, it - registers this event as waiting event in
  the database (table lsw_inst_msg_incl) - remembers the waiting
  event in the BPD's execution context.
  If an Event Gateway with multiple Intermediate Message Events is
  activated, multiple waiting events are registered in the
  database and in the BPD's execution context.
  When the BPDs navigation transaction ends and one or more
  waiting events are found in the BPDs execution context, then a
  BPDDurableMessageRecheck task is scheduled with the Event
  Manager that checks whether Durable Messages are available and
  delivers them immediately to one or more of the waiting
  Intermediate Message Events. The implementation of the
  BPDDurableMessageRecheck task calls a method, that determines
  which events from the waiting events that were remembered in
  the BPDs execution context are still registered in the
  database. This method has a parameter that determines whether
  all or only the first found waiting event should be returned.
  The value of this parameter was set to return only the first
  found waiting event and if this event does not match the
  availabe Durable Message, the Durable Message is ignored.
  

Problem conclusion

• Set the parameter so that all waiting events are returned.
