Problem summary

  • ****************************************************************
    * USERS AFFECTED: All running Wireshark traces for this        *
    *                 product.                                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: Memory leak in cclxtod while running    *
    *                      a Wireshark trace.                      *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Memory leak in cclxtod occurs when the trace files are rotated
    and the trace file format is set to ethereal/Wireshark (i.e.,
    when vport_trace_enabled=2 is specified in the configuration
    file or by default when trace is enabled dynamically via the
    cclxotm management application).
    
    If the  configured trace file format is set to text
    (vport_trace_enabled=1) the leak does not occur.
    

Problem conclusion

  • cclxotd was not freeing an internal memory block specifically
    used to manage Wireshark format trace files when the trace
    file was closed during trace file rotation.  The fixed cclxotd
    now correctly frees the memory block when the Wireshark
    format trace file is closed.
    

Temporary fix
