    being logged.
    This error is not critical.
    

Local fix

  • This error is logged because a xmfree(NULL) was
    called. The errpt entry is just informing about
    this incorrect xmfree(). This error can be ignored
    until the fix for this APAR is available and
    installed.
    

Problem summary

  • mounting udfs and consequent reboot generates GEN_XMDBG
    error-log entry.
    

Problem conclusion

  • Introduced a chcek to avoid doing a free NULL.
    

Temporary fix
