    Non Planned Task Management tasks will not go away unless
    you close them. If you never view the console to see these
    tasks, you may not realize they are there and they can cause
    slowness or even OOM in the dmgr if there are too many of them.
    

Problem conclusion

  • Added the code implementation to make the non-planned task
    management tasks to expire in 24 hours, by default, from the
    time they were created or allow an user to set the expiration
    time in hours using the deployment manager system property
    named
    "com.ibm.websphere.taskmanagement.task.nonPlannedTaskTimeout óÔé
    
    After those tasks expire, they will be removed in the next 24
    hours.
    
    The non-planned tasks created before applying this APAR are
    not impacted by this APAR fix. They still need to be removed
    using an administrative console.
    
    The system property
    "com.ibm.websphere.taskmanagement.task.nonPlannedTaskTimeout"acc
    epts an integer value to configure the amount of hours for a
    non-planned task to expire (in hours). The default value for
    this property is 24 (hours).
    
    Complete the following steps to set the system property on a
    deployment manager process.
    1. In the administrative console, click System administration >
    Deployment manager > Java and process management > Process
    definition > Java virtual machine > Custom properties.
    2. Enter the name of the custom property.
    3. Set the value of the custom property to true.
    4. Click Apply, and save your changes.
    5. Restart the deployment manager where the system property was
    set.
    
    The fix for this APAR is targeted for inclusion in fix pack
    8.5.5.19 and 9.0.5.7. For more information, see 'Recommended
    Updates for WebSphere Application Server':
