    ****************************************************************
    WebSphere Application Server attempts to delete application
    files when updating an application. If the files are locked
    the file deletion fails.
    There is a possibility that the file is locked due to a Java
    bug described at
    http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6213298
    To work around the problem, WebSphere Application Server
    requests a Java garbage collection which, if it occurs, will
    unlock the file.  However, there is no way to force a garbage
    collection and no reliable way to determine if a garbage
    collection has occurred.  For this reason, the application
    server will retry multiple times with a slight delay and a
    request for garbage collection each time.  When multiple files
    are locked, the delay can be considerable.
    

Problem conclusion

  • The code has been modified to avoid retrying to delete files
    after the first unsuccessful file deletion.
    It will still make multiple attempts to delete the first
    locked file, but will only  attempt to delete the remaining
    files one time.
    
    The fix for this APAR is targeted for inclusion in fix pack
    8.5.5.18 and 9.0.5.4. For more information, see 'Recommended
