    During restart processing, all the of storage for the file
    rules are freed.  It is possible for this heap storage to be
    freemained.  During archive initialization for the new
    configuration, the file system control blocks for the previous
    configuration are freed.  Including resetting a pointer in the
    rules control block. This reference to freed storage may
    overlay storage or abend if it is  freemained
    

Problem conclusion

  • SYSLOGD is amended to free the previous configuration file
    system control blocks before the previous rule control blocks
    are freed preventing storage overlays and abends.
