Error description

  • Problem description:
    
    This issue only occurs for the library client/manager scenario
    where:
    The ENABLELANFREE option is set to YES in the IBM Spectrum
    Protect backup-archive client
    and there is/are no drive path(s) definied for the IBM Spectrum
    Protect storage agent.
    
    The problem is caused by a lack of caching of non-existing drive
    paths for the library client
    which leads to an increasing number of sessions seen on the
    library manager.
    In such a scenario, the library manager generates new sessions
    to find a drive for the storage agent.
    If the environment or configuration is not changed, the library
    client always generates
    these unnecessary sessions to find non-existing drive paths.
    
    If the library client cached these non-existing drive path
    entries, the library
    client can search these entries without generating extra
    sessions.
    
    The consequence of this situation is that we can reach the
    maximum defined MAXSESSION
    parameter which should be increased.
    
    
    Symptom:
    
    Examine the trace log ( using message stack MSGSTACKTRACE ENABLE
    3334 8583 454 8217 408 and server trace the trace flags SESSION
    SS LANFREE LNF .) on the library manager.
    The following entries would be logged :
