APAR status

  • Closed as program error.

Error description

  • On nodes of a cluster, about 10 percentage or more units can be
    seen for the same com.presence.connect.Connect class hierarchy.
    It is causing very low performance or even OOM eventually.
    
    SessionRemovedFromCache in SessionMapperListener is called by
    AppServer when it removes a session from DynaCache. Unlike the
    sessionDestroyed method this method is guaraneteed to be called
    on all CLuster Members.
    
    A workaround will be restart server of the cluster.
