Error description

  • In IBM Process Portal, when you click a process instance in the
    Processes tab (to view the business process diagram for the
    instance in the Process Performance dashboard) or you click a
    process in the Process Performance dashboard (to view details of
     the process), a StackOverflow error might occur. This error is
    displayed in Process Portal and in the SystemOut.log file. The
    stack trace looks  similar to the following stack trace:

    The significant characteristic of the stack trace is that the
    findExternalProcesses and findTaskActivities methods, as
    previously illustrated, appear alternating many times.

Local fix

Problem summary

  • Logic that calculates historical data for a process instance can
    enter a deep recursion loop because as it traverses the
    instance's business process diagram, which can include nested
    subprocesses and linked processes. As a result, the logic might
    fail to mark a diagram as having been visited, causing repeated
    traversals of previously visited diagrams. Eventually this
    recursion loop can result in a StackOverflow error.
    

Problem conclusion

  • A fix is available for IBM BPM V8.5.5.0 that ensures that
    diagrams for subprocesses and linked processes inside a process
    instance's business process diagram are not visited more than
    once, preventing a recursion loop and StackOverflow error.
