Error description

  • As process instances and tasks are created and updated, they are
    indexed so they can be retrieved efficiently and displayed when
    you perform a quick search for instances or tasks in IBM
    Process Portal. Transaction timing issues in the Process Portal
    indexing daemon, however, can cause updates to the index to be
    missed, which, in turn, can prevent some instances and tasks
    from being retrieved and displayed when you use a quick search.
    These issues can also affect how data is displayed in the
    Processes, Process Performance, and Team Performance dashboards
    in Process Portal because these dashboards also use the index to
    efficiently retrieve and display data.
      The Lucene index commit time stopped refreshing then we have
    observed the issues in process portal where the completed
    'tasks' are appearing as still 'open'.
    Using Index Diagnostic utility we have found that the Lucene
    Index is not updating with database. We have restarted the
    JVM's couple of times and it didn't resolve the issue.
