Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty Profile                      *

    * PROBLEM DESCRIPTION: Applications sometimes do not get       *
    *                      started and logs indicate the dropins   *
    *                      monitor was started twice.              *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Occasionally the dropins monitor is started from more than one
    thread, this can lead to applications not being discovered and
    not being started.
    

Problem conclusion

  • Methods called during application monitoring could be called
    from more than one thread at the same time.  Methods were
    changed to be synchronized so that corruption of the file
    monitor state does not occur.
    
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.0.1. Please refer to the Recommended Updates page
