  • Closed as program error.

Error description

  • When you try to view a process instance diagram in IBM Process
    Portal, the Java Virtual Machine (JVM) in the IBM Business
    Process Manager (BPM) server that is responsible for retrieving
    the diagram (stand-alone server JVM or AppTarget cluster JVM)
    might encounter a hung thread and high heap memory use (and
    possibly, an OutOfMemory error). As a result, rendering the
    diagram might be slow. This issue is more likely if there is a
    high number of process instances on the server.
    
    PRODUCTS AFFECTED:
    IBM Business Process Manager (BPM) Advanced
    IBM BPM Standard
    IBM BPM Express
    

Local fix

Problem summary

  • The logic for determining whether you are authorized to view the
     diagram for the process instance is inefficient, retrieving all
     process instances which you are authorized to view (by using a
    database query) as an intermediate step.  If you are authorized
    to view a large number of process instances, this might use a
    large amount of memory and cost excessive time by the thread
    (making it at least appear to be hung).
    

Problem conclusion

  • A fix for IBM BPM V7.5.1.0 and V7.5.1.2 is available that
    improves the efficiency of the instance authorization logic,
    eliminating the retrieval of all process instances you are
    authorized to view.
