    maintenance mode. The error is logged during the attempt to
    access Application Placement Controller (APC) MBean
    

Problem conclusion

  • This issue may occur if APC, being an HAManged item, hops among
    various node agents due to constrained resources. Code changes
    were to check the validity of previous location prior to
    accessing the MBean.
