  Message CCF8107E IXGWRITE ERROR RC=00000008
  RSN=00000809 can occur when a message segment
  longer than 466 bytes is passed to the CCF AOI
  exit routine.  Storage overlays in the IMS
  private area are also possible.
  

Problem conclusion

• Ensure that truncation of messages longer than
  466 bytes take into account message header data
  to prevent overlays.
  Deterine the maximum logstream buffer size when
  CCF connects the log stream, and ensure that
  buffers written do not exceed the maximum buffer
  size.
