Error description

  • There is a possibility that when a Storage Agent starts, it can
    crash the Library Client it is connected to.
    
    In this scenario, there will be:
    
     Library Manager <-> Library Client <-> Storage Agent
    
    - At startup, the Storage Agent goes through the list of
    libraries it needs to use..
    - For shared libraries, Storage Agent talks to the managing
    server (the Library Client in this case) and asks for
    information about the server that owns each library.
      One of the pieces of information the managing server (Library
    Client) sends back about each Library Manager is it's server
    password.
    - In this scenario, one or more  of the Library Managers doesn't
    have a server password set.
    - Crash of Library Client occurs.
    
    Analysing the core on AIX platform with dbx will show:
    
    SendAttrResp(??, ??, ??) at 0x10087831c

    Once Library Client is restarted, check  "query server" and
    confirm that one or more Library Manager servers
    show as having no server password set.
