  The stack trace from the coredump file will show a problem in
  the libdb2licm.so.1 library with the following call stack:
  .
  get_linux_node_id ()
  .
  ... or the call stack will show the following stack trace:
  .
  canon_str ()
  get_disk_serial_number ()

  directory, and then append the last 4 lines from the license
  file (example db2ese.lic) into the nodelock file.  Then restart
  DB2.
